Q150 / 160 · AP EAMCET 2022 (07 Jul Shift 2) · Physics

An observer at rest experiences an electric field due to a static charge. Later he starts moving away from it then the observer experiences.

A
Only magnetic field
B
Only electric field
Correct answer
C
Electric and magnetic field
D
No field at all

Solution

As, observer starts moving away from charge, there is a relative velocity of charge with respect to observer . As, an electric and a magnetic field is associated with a moving charge w.r.t to the moving observer. Hence he experiences both fields.

Hence, the correct answer is option: 'C'.
