Which is a result of using a machine? the mechanical advantage makes the work output greater than the work input. the machine can put out force without having any force applied to it. a large force can be exerted through a long distance to have a small force exerted through a short distance. a large force can be exerted through a short distance to have a small force exerted through a long distance.

The correct answer is:

D. A large force can be exerted through a short distance to have a small force exerted through a long distance.

30 fN ( 30* 10^-15 N) and it is pointed to to -y-axis.

Explanation: In order tosolve this question we have to usethe Coulomb force given by:

F=e*E= 1.6 *10^-19 C* 1920 N/C= 30 fN the force pints in opossite direction of the electric field due to the sign of charge of the electron.
