Question

A charged particle has acceleration a=2i+xj in a magnetic field b=-3i+2j_4k find the value of x

Answer 1

: A charged particle has acceleration a vector = 2 i^ + x j^ in a magnetic field B Vector = -3 i^ +2 j^ -4 k^. To find : magnetic force acting on the particle is perpendicular on magnetic field. so, acceleration is also perpendicular on magnetic field...
