An air craft of wing span 40 ~m files horizontally in earth's magnetic field 5 10⁻⁵ ~T at a speed of 500 ~m / s . The e.m.f. generated between the tips of the wings of the air craft is

Options

  1. A0.5 ~V
  2. B1 ~V
  3. C1.2 ~V
  4. D1.5 ~V

Correct answer

B. 1 ~V

Step-by-step solution

The emf generated between the tips of the wings of the air craft is, aligned & = Blv & =5 10⁻⁵ 40 500 & =4 ~V aligned
