MCQ

A proton and an electron are placed in a uniform electric field.

A
The electric forces acting on them will be equal.
B
The magnitudes of the forces will be equal.
C
Their accelerations will be equal.
D
The magnitudes of their accelerations will be equal.

Answer

The magnitudes of the forces will be equal.

Explanation:

Proton contain positive charge = 1.6 × 10^-19 = e

Electron contain negative charge = -1.6 × 10^-19= -e

Force inoniforma electric field is = qE

$\therefore\ $The Magniludes of Electric force is equal But direction of electric force is opposite to each other.

mass of proton = 1.67 × 10^-27Kg.

mass of electron = 9.1 × 10^-31Kg.

So that Magnitudes of their acceleration will be unequal.
