Electro Magnetic Induction And Alternating Currents Question 426
Question: An aeroplane in which the distance between the tips of wings is 50 m is flying horizontally with a speed of 360 km/hr over a place where the vertical components of earth magnetic field is $ 2.0\times {{10}^{-4}}weber/m^{2} $ . The potential difference between the tips of wings would be [CPMT 1990; MP PET 1991]
Options:
A) 0.1 V
B) 1.0 V
C) 0.2 V
D) 0.01 V
Show Answer
Answer:
Correct Answer: B
Solution:
$ e=B_{v}.v.l=2\times {{10}^{-4}}\times ( \frac{360\times 1000}{3600} )\times 50 $
$ \Rightarrow e=1\ V $
