Shown in the figure below is a charged block on a spring of constant k = 106 Newtons/meter, under two different conditions. Initially there is no electric field and the block is located such that the spring is at its rest length. When an electric field of strength E = 481 Newtons/Coulomb is applied the spring is seen to stretch a distance d = 0.15 meters. k No electric field Electric Field l l 1 b l d i Which polarity is the charge on the block? 0 Positive O Negative Determine the force exerted by the spring on the block: F = :] Newtons Determine the charge on the block: Q = :] Coulombs NOTE: Be certain to enter the correct sign of charge in the final part
