JEE Main 2024 Physics question
An electron moves through a uniform magnetic field T. At a particular instant of time, the velocity of electron is m/s. If the magnetic force acting on electron is N, where e is the charge of electron then the value of B₀ is T.
Answer: 5
Solution
F⃗ = e(v⃗ × B⃗) (magnitude of the charge, taken as in the source): (3î
