Aproton has a speed of 3.50 ã 105 m/s when at a point where the potential is +100 v. later, itâs at a point where the potential is â150 v. what is the change in the protonâs electric potential? what is the change in the potential energy of the proton? what is the work done on the proton?

(a). The change in the protons electric potential is 0.639 kV.

(b). The change in the potential energy of the proton is

(c). The work done on the proton is .

Explanation:

Given that,

Speed

Initial potential V=100 V

Final potential = 150 V

(a). We need to calculate the change in the protons electric potential

Potential energy of the proton is

Using conservation of energy

Put the value into the formula

(b). We need to calculate the change in the potential energy of the proton

Using formula of potential energy

Put the value into the formula

(c). We need to calculate the work done on the proton

Using formula of work done

Hence, (a). The change in the protons electric potential is 0.639 kV.

(b). The change in the potential energy of the proton is

(c). The work done on the proton is .

i was thinking more like reflects green light, just not sure
