Two particles are held in equilibrium by the gravitational and electrostatic forces between them. Particle-A has mass `m_(alpha)` and charge `q_(alpha) ` and particle-B has mass `m_(b)` and charge `q_(b)`. The distance between the charges may cause the chages to accelerate towards one another ?

A

`m_(a)` is doubled and `m_(b)` is halved

B

`m_(a)` is doubled and `m_(b)` is doubled

C

`q_(a)` is doubled and `q_(b)` is doubled

D

`d` is doubled
