Practicing Success
A straight wire of mass 200 g and length 1.5 m carrying a current of 2 A is placed in a uniform magnetic field at right angles to its direction, is suspended in mid air. The magnitude of magnetic field is: (g = 9.8 m/s2) |
0.65 T 1.5 T 3.3 T 6.5 T |
0.65 T |
The correct answer is Option (1) → 0.65 T |
