Moving Charge | MCQs

Q1: A positive change moving with a constant velocity v enters a region of a uniform magnetic field pointing out the page. What is the direction of the magnetic force on the charge?

مستقل رفتار کے ساتھ چلنے والی ایک مثبت تبدیلی صفحہ کی نشاندہی کرنے والے یکساں مقناطیسی فیلڈ کے ایک خطے میں داخل ہوتی ہے۔ چارج پر مقناطیسی قوت کی سمت کیا ہے؟

A. None of these
B. To the bottom of the page
C. Right
D. To the top of the page

Explanation

The magnetic force on a moving charge is given by Lorentz force: $F = q (v \times B)$

Using the right-hand rule, point your fingers in the direction of velocity (v), curl them toward the magnetic field (out of the page), and your thumb points in the direction of force.

For a positive charge, the force is toward the top of the page.
