Question

An object after deforming

• A. may have different centre of mass.
• B. have same centre of mass
• C. doesn't change its centre of gravity
• D. none of the above

Answer 1

Answer: (A)

may have different centre of mass.

Centre of mass is a point on a physical body which behaves as if the whole mass is concentrated over there. Whenever a force acts on a body it appears to be acting on the centre of mass.

The centre of mass depends upon how the particles of the body are scattered around it. It is closer towards the heavier regions of the body as compared to the lighter regions. Whenever an object is deformed, its heavier regions may change their locations. As a result, the centre of mass may change its location
