Question

A small charged bead (mass = m, charge = Q) can slide on a circular frictionless, fixed insulating wire frame. A point like dipole (dipole moment P) is fixed at the centre of circle. Bead is released from rest from given position 'A'. (Neglect gravity) 'D'

Choose incorrect statements.

(A) Speed of bead is maximum at point 'B'.

(B) Normal force on the bead at point 'A' is zero

(C) Tangential acceleration of bead at point 'A' is zero 

(D) Motion of bead is periodic.

Answer 1

Correct option  (C) Tangential acceleration of bead at point 'A' is zero
