JEE Advanced 2026 Physics question

Consider an electric dipole comprising two charges and each with mass , separated by a fixed distance and initially at rest with its dipole moment pointing along . A uniform electric field is turned on at time and it is turned off at , when the dipole moment makes an angle with . Neglecting any sources of energy loss, correct option(s) is/are:

• (A)The center of mass of the dipole is deflected towards in the presence of the field.
• (B)If the magnitude of the final angular velocity , then .Correct
• (C)If , then the change in kinetic energy of the dipole is given by .
• (D)For , the dipole rotates around its center of mass with a constant angular velocity after .Correct
