A coil of resistance is placed in a magnetic field. If the magnetic flux (Wb) linked with the coil varies with time t (sec) as . The current in the coil at t = 2 sec is 0.5 A 0.1 A 2 A 1 A
Multiple Choice Options
- A 20 m s _ 1
- B 30 m s _ 1
- C 5 m s _ 1
- D 10 m s _ 1
Step-by-Step Verified Solution
Here, m = 1000 kg, R = 90 m, _ = 45�
For banking, tan _ _ = v 2 R g
_ v = R g tan _ _ = 90 _ 10 _ tan _ 45 o = 30 m s _ 1
