What is the total amount of work required to

move a proton through a potential difference of

  1. volts?

(1) 1.60 × 10^–21 J (3) 1.00 × 10^2 J

(2) 1.60 × 10^–17 J (4) 6.25 × 10^20 J

Verified Answer :

Answer:

\(W = 1.6 \times 10^{-17} J\)

Explanation:

Work done to move a charge through a given potential difference is

\(W = q(\Delta V)\)

here

q = magnitude of charge

\(\Delta V\) = potential difference

here it is given that charge of the particle is same as charge of proton

\(q = 1.6 \times 10^{-19} C\)

\(\Delta V = 100 V\)

now we have

\(W = (1.6 \times 10^{-19}) (100)\)

\(W = 1.6 \times 10^{-17} J\)
