JEE Main 2022 — Electrostatics Question with Solution
From: JEE Main 2022 (Online) 24th June Morning Shift
Question
A vertical electric field of magnitude 4.9 105 N/C just prevents a water droplet of a mass 0.1 g from falling. The value of charge on the droplet will be :
(Given : g = 9.8 m/s2)
Choose an option
Show full solutionCorrect option: B
Correct answer
B2.0 109 C
Step-by-step explanation
Since the droplet is at rest
Net force = 0
mg = qE
= 2 109 C
