MHT CET 2026 Physics question
An aeroplane having a wing span of 30 m flies due north with the speed of 170 m/s. Magnetic field B = T. The potential difference between the tips of the wings will be
Answer: (B)
Solution
The wings cut the magnetic field lines, so a motional emf is induced between the wing tips (B taken as the component of the field perpendicular to the plane of motion, as given). 10^{-5})(30)(170)$ =
