Basically you need to do an integration, multiplying each mass point by its x-coordinate. Finally you divide by the total mass. Similarly for the y-coordinate.

What is the organization of the subatomic particles in an atom?
The protons and neutrons are at the centre in a mass called the nucleus and the electrons revolve around the nucleus in circular paths called orbits.
How you can derive mass to charge ratio equation?
It is a simple ratio charge/mass or e/m .
What is the significance of centre of mass of a system?
scxv cx
How is the mass of a pencil different from its weight?
The mass will always stay the same but the gravitational pull towards the centre of the earth (weight) will change.
How do you find the center of mass of a triangle?
its where the medians all meet, ie if you draw a line from each vertx to the midpoint of the opposite side where they all meet is the centre of mass its where the medians all meet, ie if you draw a line from each vertx to the midpoint of the opposite side where they all meet is the centre of mass
How can you find center of mass of solid hemisphere?
Take an elemental mass on the solid hemisphere. Let the mass be in thin form of discs. The centre of mass lies at the centre of the disc. Integrate the whole function to get the c.o.m.
Is it necessary that centre of mass should always lie inside the body?
No, it may lie outside the body. In case of a circular ring, it is at the centre of the ring which is outside the mass of the ring.
How is the milky way galaxy similar to the solar system?
Its similar in shape, both are more or less disc shaped. Both have a large mass at the centre. Both have smaller bodies orbiting this mass.
What is the organization of the subatomic particles in an atom?
The protons and neutrons are at the centre in a mass called the nucleus and the electrons revolve around the nucleus in circular paths called orbits.
Brandon throws a flying disc with a force of 8 N If the disc has an acceleration of 4 ms2 what is the mass of the disc?
Brandon throws a flying disc with a force of 8 N. If the disc has an acceleration of 4 m/s2, what is the mass of the disc?
What is difference between center of mass and center of gravity?
centre of mass is nothing the mass (volume) situated at centre which is not at all use full for pt of control. but centre of gravity is that pt at which we can hold the total mass or body .
How you can derive mass to charge ratio equation?
It is a simple ratio charge/mass or e/m .
What is the difference between center of mass and center of buoyancy?
Centre of mass is a convinient point where whole mass of the body is supposed to be acting and for bodies of small shape it concides with the geometrical centre. Centre of bouancy is the centre of the immersed portion of the body inside the liquid.
Why is the weight of a body zero at the center of the earth?
At the centre of the Earth, or any body for that matter, the mass of the Earth is centralised at the centre, At the centre of the earth there is no weight attributable to the earth's mass. But there is weight (a force) attributable to the sun's mass, neatly balanced out by the speed of the earth in its circular orbit. So the weight is mv2/r instead of mg (m= a mass placed at the centre, v=velocity in orbit, r= distance to sun). If the earth slowed to a stop, it, and everything at its centre would accelerate towards the sun. If somehow you could nail the earth down so it didn't fall in, that weight would be measureable with a spring balance. Ignoring galactic and intergalactic forces. I guess that's sophistry really.

How did sun and planets form from sun and dust?
Nobody knows for certain. Most scientists think that the Sun, Earth and other planets (the Solar System) were formed from a mass of dust and gas. Nearly 5,000 million years ago, this mass started to shrink, and then spin and flatten into a disc. The centre of the disc spun fastest. This became the Sun. The rest of the material turned into the planets.
What is an apoapsis?
An apoapsis is the point of a body's elliptical orbit around the system's centre of mass where the distance between the body and the centre of mass is at its maximum.
