An aircraft with a wingspan of 40 m flies a speed of 1080 km `hr_(1)` in the eastward direction at a constant altitude in the northern hemisphere, where the vertical component of earth's magnetic fieldis `1.75 xx 10^(-5)` T. Find the e.m.f. that develops between the tips of the wings.

A

0.34 V

B

2.1 V

C

0.5 V

D

0.21 V

Text Solution

Verified by Experts

The correct Answer is:
D
`e=B_(V)vl`
= `1.75xx10^(-5)xx1080xx5/18xx40=0.21V`.
