A particle of mass 1×10−26 kg and charge +1.6×10−19 C travelling with a velocity of 1.28×106 m/s along positive direction of x-axis enters a region in which a uniform electric field E and a uniform magnetic field B are present such thatEz=−102.4 kV/mandBy=8×10−2 Wb/m2The particle enters this region at origin at time t=0 . Then,
(a) net force acts on the particle along the +ve z-direction
(b) net force acts on the particle along -ve z-direction
(c) net force acting on particle is zero
(d) net force acts in xz-plane
