A magnetic field of 2 × 10–2 T acts at right angles to a coil of area 100 cm2, with 50 turns. The average e.m.f. induced in the coil is 0.1 V, when it is removed from the field in t sec. The value of t is
-
- 10 s
- 0.1 s
- 0.01 s
- 1 s
Correct Option: B
| e = | = | = | ||||
| t | t | t |
| t = | = | = 0.1 s | ||
| e | 0.1 |
