Three charged particles are located at the corners of a right angled triangle and have charges
q1 = q3 = 40 nC and q2 = 10 nC. Find the magnitude and direction of the electric field at point
P due to these particles.
A physics instructor, in a lab, charged an electrostatic generator to 25 μC, then carried it into the lecture hall. The net electric flux in Nm2/C through the lecture hall walls is:
You measured that your flashlight experiences a current of 0. 40 A when you insert a brand new 3.0 V Energizer battery. We can take it that the internal resistance of a new battery is almost zero.
