JEE Main 4 April 2026, Shift 2, Physics Q36

Question 36 of 75 in this shift, Physics question 11 of 25, Section A.

A rigid dipole undergoes a simple harmonic motion about its centre in the presence of an electric field

\vec E_1=E_0\,\hat x

. If another electric field

\vec E_2=2E_0\left(\hat y+\hat z\right)

is introduced to the system, what will be the percentage change in the frequency of the oscillation (approximate)?
