The Magnitude and Sign of a Point Charge
Not what you're looking for?
A point charge (m = 1.0 g) at the end of an insulating string of length 46 cm is observed to be in equilibrium in a uniform horizontal electric field of 9200 N/C, when the pendulum's position is as shown in attached diagram, with the charge 2.0 cm above the lowest (vertical) position. If the field points to the right as shown in the diagram, determine the magnitude and sign of the point charge.
