A tennis racket hits a tennis ball. The racket has a mass that is four times greater than the tennis ball. Compared to the force exerted on the ball by the racket, the force exerted on the racket by the ball is A.) four times smaller
B.) the same
C.) 16 times smaller
D.) four times greater

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
