Teaching UP PGT Mock Test Series 2024 Physics Moving Charges and Magnetism Motion in a Magnetic Field
A charge of 0.2 C moves with a velocity \(\rm\overrightarrow{v}\) = (3î + 4ĵ) m/s in a uniform magnetic field of B = 5 k̂T. What is the magnetic force experienced by the charge?
1
(4î + 3ĵ) N
2
(4î − 3ĵ) N
3
(3ĵ − 4î) N
4
(−4î − 3ĵ) N
