Question

Consider the following two statements.

(1) As a charged particle is taken from a region of lower potential to a region of higher potential, its potential energy always increases.

(2) The potential energy of an electron-proton pair is positive.

The incorrect statement(s) is/are

​​​​​​​$[$0.77 Mark$]$

• A. Only (1)
• B. Only (2)
• C. Both (1) and (2)
• D. Neither (1) nor (2)

Answer 1

The correct option is C Both (1) and (2)

In case of a positive charge taken from lower potential to higher potential, then the potential energy increases.

Whereas, if a negative charge taken from lower potential to higher potential, the potential energy decreases, since, at a location of higher potential, the potential energy will be less because $U=qV$.

For electron-proton pair, $U=\frac{-k{e}^2}{r}<0$.

So, both the statements are incorrect.
