BITSAT 2024 | Moving Charges and Magnetism Question 1 | Physics

The straight wire $ A B $ carries a current $ I $. The ends of the wire subtend angles $ \theta_{1} $ and $ \theta_{2} $ at the point $ P $ as shown in figure. The magnetic field at the point $ P $ is

BITSAT 2024 Physics - Moving Charges and Magnetism Question 1 English

$ \frac{\mu_{0} I}{4 \pi d}\left(\sin \theta_{1}-\sin \theta_{2}\right) $

$ \frac{\mu_{0} I}{4 \pi d}\left(\sin \theta_{1}+\sin \theta_{2}\right) $

$ \frac{\mu_{0} I}{4 \pi d}\left(\cos \theta_{1}-\cos \theta_{2}\right) $

$ \frac{\mu_{0} I}{4 \pi d}\left(\cos \theta_{1}+\cos \theta_{2}\right) $

An electric current I enters and leaves a uniform circular wire of radius r through diametrically opposite points. A charged particle q moves along the axis of circular wire passes through its centre at speed v. The magnetic force on the particle when it passes through the centre has a magnitude.

$${{qv{\mu _0}I} \over {2\pi r}}$$

$$qv{{{\mu _0}I} \over {\pi r}}$$

$${{qv{\mu _0}I} \over r}$$
