Aproton is moved so that its electric potential energy increases from 4.0 × 10-14 j to 9.0 × 10-14 j. the magnitude of the charge on a proton is 1.602 × 10-19 c.

what is the electric potential difference through which the proton moved?

2.5 × 105 v
3.1 × 105 v
5.6 × 105 v
8.1 × 105 v

Electric potential difference is option (b) i.e.

Explanation:

It is given that,

The magnitude of charge on the proton,  

The electric potential energy increases from to            

We have to find the electric potential difference through which the proton moved.

The relation between electric potential energy and electric potential difference is given by :

Hence, this is the required solution.

this a false

explanation:

none, its a machine
