A particle is having mass m & charge +q is projected horizontally from point O . Electric field is present and is directed vertically downward .

A particle of mass m and charge -q is released from rest in a uniform electric field. If there is no other force on the particle, the dependence of its potential energy on the distance x travelled by it is correctly given by (assume initial potential energy to be zero ,graphs are schematic and not drawn to scale)

Between two horizontal parallel plates, uniform electric field E directed vertically downward. A charged particle (q,m) remains in equilibrium in vaccum between the plates. Find shortage/excess of electrons in the charged particle .

A projectile of mass m is thrown vertically up with an initial velocity v from the surface of earth (mass of earth = M). If it comes to rest at a height h, the change in its potential energy is
