A 25- cents coin is placed on top of an index card which is placed on top of a plastic container. When the index card is flicked with a finger sideward, the coin does not move

with the direction of the force, rather it falls inside the container. What do you think is the

reason why it does not move with the direction of the force?

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
