A projectile is projected in the earth s gravitational with initial kinetic energy E The horizontal of the projectile range is R If the mass of the projectile is 1 kg then the angle of projection of the projectile will be equal to A sin gR 2E C 0 5sin gR 2E D 4sin gR 2E B 2sin gR 2E Three solid spheres each of mass m and radius R are released from the position shown in figure The speed of any one sphere at the time of collision would be
