A nega t ive charge with a velocity vector v enters a magnetic field directed in

Question

A negative charge with a velocity vector v enters a magnetic field directed into the page. Which vector a, b, c, d, e and f, represents the direction of the magnetic force on this charge?

A negative charge with a velocity vector v enters a magnetic field directed into the page. Which vector a, b, c, d, e and f, represents the direction of the magnetic force on this charge?

The drawing shows four situations in which a positively charged particle is moving with a velocity through a magnetic field . In each case the magnetic field is directed out of the page toward you, and the velocity is directed to the right. In only one out of these drawings is the magnetic force physically reasonable. Which drawing is it?

Explanation / Answer

7) e

using right hand rule we determine the direction.

8) 1
using right hand rule we determine the direction.

take your fingers in the direction of v and culr towards B, then your thumb indicates the direction of magnetic force.

This is valid for postive charges only.

for negative charges the direction of force is opposite to the direction of thumb .
