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.

How much work is done when a 4.0 newton box is carried horizontally a distance of 2.0 meters at a constant velocity?
If the box ended up at the same height above the floor as it started, then no gravitational potential energy was added to the box in the form of work. It doesn't even matter if the box moved up or down on the way. Of course, work is done, and calories are expended. That's only because your body is not 100% efficient, and it takes work to move arm and leg muscles, walk, breathe, etc. But no work is done on the box as it moves horizontally.
How much krypton is in the human body?
there is no krypton in the human body
Why doesn't the electron lose twice as much energy when it moves in two levels as it loses when it moves only one energy level?
The energy gaps between levels are not all the same.
What is a proposed explanation or answer to scientific explanation?
A hypothesis or a theory depending on how much experimentation was done up till that point and how much information it is based on.
Can a controlled hypothesis be called a theory?
No. Much more has to be done to prove any hypothesis a theory.
How much work may be done on a body that moves in a circle with constant speed?
If there's a body moving in a circle with constant speed, and you come along and do work on it, then either its speed will change, or it will depart from the circle, or both. The force that's keeping it on the circular path is not doing any work on it.
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
How much work is done on a satellite in a circular orbit about Earth?
The work done on a satellite in a circular orbit around Earth is zero because the gravitational force acting on the satellite is perpendicular to the direction of motion, so no work is done to maintain the orbit.
If you push a box forward and the box moves forward you have done how much work?
You have only done as much external work on the box as the distance it moves: work = force x distance. If it does not budge no work is done on the object. You have done "internal" work on your muscles which converts to heat energy, but technically speaking, no external work is done on the object
How much work is done when a force of 2n moves a body through a distance of 10 cm in direction of the force?
force=2N distance moved=o.1 m work done=? work done=force(N)*distance moved (M) work done=2*o.1 work done= 0.2 watts
How much work is done when a force of 30 N moves an object a distance of 3 m.?
i dont no
How much work is done when a N force moves block 4m?
The work done is equal to the force applied multiplied by the distance moved in the direction of the force. In this case, if a force of N moves a block 4m, the work done would be N multiplied by 4m.
How much work is done if you hold a 50lbs box for 5 hours?
No work is being done. Work is when an object moves in the same direction as the force applied to it.
How much work is done when a force 14 N moves an object 6 meters?
The product of these two numbers, assuming the force acts in the same direction as the object moves.
How much work is done when 5n force moves a block 4m?
The work done is calculated using the formula: Work = Force x Distance. Therefore, the work done is 20n*m.
How much work is done when a force of 30 n moves an object a distance of 30 m?
The work done is calculated by multiplying the force by the distance the object moves in the direction of the force. So, the work done would be 30 N * 30 m = 900 J.
How much centripetal force is needed by a body moving in uniform circular motion if the speed is doubled?
Four times as much. The relevant formulae are F = ma, and a = v2/r.
