JEE Main 2020 — Electrostatics Question with Solution
From: JEE Main 2020 (Online) 6th September Evening Slot
Question
Two identical electric point dipoles have dipole moments and and are held on the x
axis at distance '' from each other. When released, they move along the x-axis with the direction
of their dipole moments remaining unchanged. If the mass of each dipole is 'm', their speed when
they are infinitely far apart is :
