JEE PHYSICS MCQ: ELECTRIC FIELDS AND CHARGES

1 Medium

1 of 1

Application +4 | -1

A dipole has two charges

+1 \mu {C}

and

-1 \mu C

and each have mass

1 {~kg}

. The separation between the charges is

1 {~m}

. An electric field

20 \times 10^3 {v} / {m}

is applied on the dipole. If the dipole is deflected through

2^{\circ}

from the equilibrium position, time taken by it to come to the equilibrium position again is

View answer and explanation

Correct option: A

2.5 \pi {sec}

Option A (

2.5 \pi {sec}

) is correct because it's calculated using the formula for the time period of a torsional pendulum.

Assertion:- Electric field lines do not cut at any point.
Reason:- At any point, there is only one direction of electric field. Statement-I: A positive point charge is brought in an electric field, the electric field at neary by point will increase
