A charged particle of mass m and charge q is released from rest in an electric field of constant magnitude E . The kinetic energy of the particle after time t is

A charged particle of mass m and charge q is released from rest in an electric field of constant magnitude E . The kinetic energy of the particle after time t is

A charge q moves in a region, where electric field vecE and magnetic field vecB both exist, then the force on it is

A ball of mass m is projected from ground making an angle q to the horizontal. There is a horizontal wind blowing in the direction of motion of the ball. Due to wind the ball experiences a constant horizontal force of (mg)/(sqrt(3)) in direction of its motion. Find theta for which the horizontal range of the ball will be maximum.
