Question

2a) Three electrons are placed on corners of a square with sides of length 14 cm. Calculate the electric potential at the center of the square.

b) Calculate the electric potential energy of two +7.1 x 10^-6 C charges separated by 0.13 m.

c) A 1.5 V battery contains 950 J of energy. Calculate how long it would take for this battery to completely drain if it was wired to a 9 ohm resistor.

d) A -3.1 C charge moving at speed 260 m/s experiences a magnetic force of magnitude 1.45 N. Calculate the magnitude of the magnetic field that creates the force.
