Five point masses `m` each are kept at five vertices of a regular pentagon. Distance of centre of pentagon from any one of the verticle is 'a'. Find gravitational potential and filed strength at centre.

Text Solution

Verified by Experts

The correct Answer is:
A
`V = 5((-Gm)/(a)) = - (5 Gm)/(a)`
For E Five vectors of equal magnitudes, when added as per polygon law of vector. Hence, net `E` is zero .
