Question

Question 21 Two particles have the same net negative charge, -q. but different masses, m and M. Both particles are initially moving directly toward the right along the x-axis with the same velocity as they enter the uniform electric field. If the larger mass, M, is exactly twice the smaller mass, m (i.e, M 2m), which of the following best describes the motion of the larger mass, M. -q Select the correct answer CHECK ANSWER 2 of 3 attempts used LAST ATTEMPT O Mass M will be deflected downward with the same acceleration as mass m O Mass M will be deflected upward with twice the acceleration as mass m. O Mass M will be deflected downward with half the acceleration as mass m.

Answer 1

F = m a

eE = ma

for constant e E. mass is inversely proportional to acceleration

so

acceleration of M2 is half of acceleration of M1 in upward direction

direction = upwards

acceleration = half of m

comment in case any doubt, will reply for sure.. goodluck
