When forces F1, F2, F3, are acting on a ...

When forces `F_1`, `F_2`, `F_3`, are acting on a particle of mass m such that `F_2` and `F_3` are mutually perpendicular, then the particle remains stationary. If the force `F_1` is now removed then the acceleration of the particle is

A

`F_1//m`

B

`F_2F_3//mF`

C

`(F_2-F_3)//m`

D

`F_2//m`
