An electron is released from rest in a uniform electric field of magnitude 2.16 x 10^4 n/c. calculate the acceleration of the electron. (ignore gravitation.) number units

Acceleration of the electron will be          

Explanation:

We have given electric field

Charge on electron

So force in the electron

Mass of electron

Now according to newton second law

F = ma, here m is mass and a is acceleration

So

So acceleration of the electron will be

it is the second option.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
