A positive point charge `q_(1)` is placed at `(a,0)` and another positive point charge `q_(2)` is placed at (0,a) . Find the force acting on `q_(1)`.

A conducting spherical shell is earthed. A positive charge +q_1 is placed at the center and another small positive charge +q_2 is placed at a distance r from q_1 . Ignore the effect of induced charge due to q_2 on the sphere. Then the coulomb force on q_2 is

Two equal positive point charges 'Q' are fixed at points B (a, 0) and A(-a, 0). Another test charge q_(0) is also placed at O (0, 0). Show that the equilibrium at 'O' is (i) Stable for displacement along X-axis (ii) Unstable for displacement along Y-axis.
