Answer:
(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 .
