Q1- A proton is released from rest where an electric field of 640 N/C exists. (a) what is the acceleration of proton? (b) how long does it take to reach a speed of 1.2*106 m/s (c) How much distance does it travel during this time.
Q2- Three point charges are placed on the vertises of a triangle as shown. Find the net force on charge q2 if a = 1.0 m
• q1 = 3*10-6 C
a
• a • q2 = 2.5*10-6 C
q3 = - 2*10-6 C
