C10 Consider two parallel electron beams moving in same direction Cross sectional area of each beam is A v is speed of electrons in the beam nis electron concentration in the either beam r is distance between the two beams e is electronic charge Cross sectional dimension of each beam is small compared to r Choose the correct answer 1 Electric force acting on an element of length chosen in any of the beams is e n A l e n A Teor 2 or 1 3 e n A Teor e n A l 4 2 or 2 Magnetic force acting on an element of length chosen in any of the beams is 1 Hoe n v AE 2 r 1 Hoe n v A 2 r 2 3 2c 2 4 3 3 Ratio of magnetic force to electric force acting on an element of length in any of the beams is Hoe n v A 2 r 2 Hoe n v Al 4fr
