If a projected charge passes through a zero gravity its speed may be constant then find possible cases of electric and magnetic field in that region
Answers
Given:
A projected charge passes through a zero gravity space such that its speed remains constant.
To find:
Possible cases of electric and magnetic field in that region.
Solution:
Both electric and magnetic field has to be present in that region in order to nullify each other's force such that the projected charge moves with constant speed.
Let's consider that the Electric field is directed upwards.
So, the charge will experience electrostatic force in the upward direction.
Again, the magnetic field has to be directed out of the plane of the paper.
So, the moving charge will experience magnetic force in the downward direction.
These two forces will cancel each other and the projected charge will move in a straight line with constant speed.
Refer to attached diagram.
Explanation:
E and B cancel each other as suppose E is in upward direction and B is out of plane of paper .. so it will exp downward force cancelling each other
