Answer 1

Part A Part-D Given a = – 5.40mc B - 1.25tü &=- (3.00 x 10 W) + (7-60 x 10 7 W) } The all three components of velocity can be determined by measuny force Answer No. magnetic force on a moving charge particle of velocity v. = a (x ) - (3.00 x103) i + (7.60 x 10 w) } = -(5.40 x 10 c) ( vel + y ) + Up 2) × (-1.25 t)u] . 6.75 X6" [ - vx I + vy?] comparing i and i from both sides- 3.00x107 6 = – 0.04 ms. 6. 75 x 10 Vx= - 7-60x10 6.75 110-6 = -0.112 m/s. Vz=0 x component of velocity = – 0.112 m/s.
