How much work is done on a body of mass 1kg whirling on a circular path of radius 5m?

Zero, in this case acting force is perpendicular to the direction of displacement...
Reason.....
It is because here the angle is 90 degree and when there is an angle then the force is equal to F cos x * d= F *cos 90*0= 0
Therefore work done=0

What is the work done by a body moving along a circular path?
i think it is zero
When force is and what direction of motion no work is done?
Perpendicular (90o). Like whirling an object around on a piece of string. The force is along the string, at right angles to the motion.
Differentiate batween the work done on the body and work done by the body?
note: Work done is = force applied to a body * time taken by the body When we apply a force on to an object such that the object displaced in the direction of force, then some unit of work is done on the body. When a body sets another body into motion by applying a force, in unit time, that body is considered as it had done a unit of work
Is it possible that a body be in accelarated motion under a force acting on a body yet no work is being done by the force?
Yes, that is possible. For example, an object in circular motion, accelerated towards the center. The force (and the acceleration) is normal (perpendicular) to the movement; thus, the dot product between the force and the displacement is zero.
How much work is done by the centripetal force on a body along a circular path?
Zero. W = F* d cos (Theta) W = Tension * displacement * cos (90) The force is perpendicular to the objects motion (or displacement of the object) W = T * d * 0 W= 0

What is the moment of inertia of a disk of radius 12cm and mass 2.4kg from whose edge a circular portion of radius 3cm has been cut off?
It can be done, but it would require taking an integral for the moment of inertia of each particle of the disc... something i don't have the time to do right now ^^;
What is a circular skirt?
A circular skirt is a skirt that is done by cutting just a circle out of a piece of fabric.
What is circular knit fabric?
Knitting is formed in one or a combination of two basic forms: flat or in the round. Flat knitting is typically done on straight needles and circular knitting is typically done on circular needles or double point needles. When people think of knitting in the round, typically they mean knitting a tube shape, such as a sock or hat. But it is also possible to knit actual circles instead of tubes, such as when one makes circular shawls, table cloths, or doilies. Whether knitting a tube or a flat circle, the technique is the same. The difference is that in tube knitting few if any increases or decreases are made and in knitting a flat circle increases must be made such that as the radius of the circle doubles the number of stitches on the needle also double. Mathematically, it looks like this: c = 2 * pi * r, where c is the circumference and r is the radius. The ratio of the circumference to the radius must always remain 2 * pi or the piece will not remain flat.
When an object moves circular path what is the work done specify reason?
Zero work done
What is the volume of water in a hemisphere with given radius of hemisphere and height of water?
Can not be done without the 'Given' radius and height.
When body moves in a circular path how much work is done by the body?
Zero. This is because when a body when around in a circle, a centripetal force acts on the particle to keep it at that fixed distance from the centre. At each point, the force and the displacement are perpendicular to each other. Hence no work is done. The answer is NOT Zero! A Force is required in the direction of motion around the circle. At every point (an infinite number of them) there must be a Force PERPENDICULAR to the Centrifugal and Centripetal Forces or the object would not move. Therefore the amount of work done is the product of that FORCE times the circumference of the circular path, if only considering one revolution.
When force is and what direction of motion no work is done?
Perpendicular (90o). Like whirling an object around on a piece of string. The force is along the string, at right angles to the motion.
What is a circular combination?
^ Thanks for helping kanika! I was wondering whether there is a formula to derive the number of possible combinations (for a circular arrangement). If you do know the answer, please help!
Diff between linear and circular convolution?
there is a big difference between circular and linear convolution , in linear convolution we convolved one signal with another signal where as in circular convolution the same convolution is done but in circular patteren ,depending upon the samples of the signal
What should be the angle between the direction o foce and the direction of motion of a body so that the work done is zero?
Work is zero when the force is perpendicular to the direction of motion, as it is, for example, in a circular gravitational orbit.
How to calculate the volume of a globe?
measure radius, and cube it. multiply the cubed radius by pi. multiply that answer by 4/3. done
