a) If a proton moved from a location with a 5.0 V potential to a location with 7.5 V potential, would its potential energy increase or decrease? Explain. b) If an electron moved from a location with 7.5 V potential to a location with a 5.0 V potential, would its potential energy increase or decrease? Explain

A. The potential energy of the positively charge proton from 5v to 7.5v will increase because in an electric field work is done on the proton to move it to a point of higher potential

B. when an electron is moved from 7.5v to 5v it loses potential energy due to the charges lost so as to bring it to a point of lower potential

Explanation:

divide the right side by the left side

0.024÷1.2=0.02 for example

12000j is work done
