A jet plane is travelling west at 450 `m//s`. If the horizontal component of earth's magnetic field at the place is `4 xx 10^(-4) T` and the angle of dip is `30^(@)`, find the e.m.f. induced between the ends of wings having a spam fo 30 m.

Explanation

To find the induced electromotive force (e.m.f.) between the ends of the wings of a jet plane traveling west, we will follow these steps:

### Step-by-Step Solution:

1. **Identify Given Values:**
- Speed of the jet plane, \( v = 450 \, \text{m/s} \)
- Horizontal component of Earth's magnetic field, \( B_H = 4 \times 10^{-4} \, \text{T} \)
- Angle of dip, \( \delta = 30^\circ \)
