Hello student,
Fnet=ma
a = acceleration of charge of particle at A = 0
So Fnet = 0.
Thanks and Regards

All the three particles have same charge therefore they should repel each other.The charge at point A will experience repulsive force from point B and C.Similarly point B will experience force from A and C and point C will experience force from A and B . The resultant of the forces from point B to A and C to A will be cancelled out the resultant of force from A to C and A to B and therefore net force is zero
I hope this is helpful
