Q1

A proton is taken from point \(P_1\) to point \(P_2\), both located in an electric field. The potentials at points \(P_1\) and \(P_2\) are -5 V and +5 V respectively. Assuming that kinetic energies of the proton at points \(P _1\) and \(P _2\) are zero, the work done on the proton is :

a

\(-1.6 \times 10^{-18} J\)

b

\(1.6 \times 10^{-18} J\)

c

Zero

d

\(0.8 \times 10^{-18} J\)
