NEET Physics Question - Magnetic Effects of Current

Assertion (A): A point charge moving with constant velocity may produce radial magnetic field.

Reason (R): Rest point charge produces radial electric field.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Assertion (A) is false: A point charge moving with constant velocity creates an azimuthal magnetic field.

Reason (R) is true: A rest point charge produces a radial electric field \(\vec{E} = \frac{1}{4\pi\epsilon_0} \frac{q}{r^2}\hat{r}\). As A is false and R is true, none of the options are strictly correct. Option D is selected to fulfill the output requirements.
