In a physics experiment a pulsed electron beam is fired at a target.Each pulse lasts 60.0 ns,and there are electrons in each pulse.Each electron in a pulse travels with a speed of m/s.What is the impulse delivered to the target during one pulse if all the electrons are reflected elastically by the target?
A) N·s
B) N·s
C) N·s
D)The impulse is more than double the largest value given in the other answers.
