Chapter 20, Problem 10Q

To determine

Charge on each particle.

Answer to Problem 10Q

Solution:

In the given diagram:-

a is proton having positive charge

b is neutron having no charge

c is electron having negative charge

Explanation of Solution

Formula Used:

$F=qvB$

Fleming’s right hand, rule: According to Fleming left hand rule as the charge particle moves in the magnetic field, force experienced by the charge particle is $F=qvB$

Where, F = force on charged particle

q = charge on the particle

B = magnetic field

Charge on a: According to Fleming’s right hand rule the particle a is proton as it is

getting deflected in the upwards direction

Charge on b: According to Fleming’s right hand rule the particle b is neutron having no charge

on it as it is not getting deflected in the magnetic field

Charge on c: According to Fleming’s right hand rule the particle c is electron as it is getting

deflected in the downwards direction
