Question

The motion of a charged particle can be used to distinguish between a magnetic field and electric field in a certain region by firing the charge

• A. Perpendicular to the field
• B. Parallel to the field
• C. From opposite directions
• D. With different speeds

Answer 1

The correct option is B Parallel to the field

$Given:$ The motion of a charged particle can be used to distinguish between a magnetic and electric field in a certain regionby firing the charge.

$Solution:$Parallel to the field. Magnetic force will not act so will have no effect on charge but electric force will act and charge will accelerate and deaccelerate.

$So,the$ $correct$ $option:B$
