Four particles, each with mass m are arranged symmetrically about the origin on the x axis. A fifth particle, with mass M, is on the y axis. The direction of the gravitational force on M is:

A

`uarr`

B

`darr`

C

`larr`

D

`to`

Text Solution

Verified by Experts

The correct Answer is:
B
In horizontal direction, the forces will cancel each other while in vertically downward direction the components of all the forces will add up to give the resultant. Hence, direction of force on M is vertically downward.
