Q1 two point charges q1 -67 mu c and q2 30 mu c are, Ask an Expert

Academics

Q1. Two point charges, Q_1 = -6.7 mu C and Q_2 = 3.0 mu C are located between two oppositely charged parallel plates. The two charges are separated by the distance of x = 0.33 m. Assume that the electric field produced by the charged plates is uniform and equal to E = 7.9×104 N/C.

Q2. A 21 g bullet travelling at 255 m/s is fired into a 0.452 kg wooden block anchored to a 100 N/m spring. How far is spring compressed to the nearest thousandth of a meter?
