Question

5)A solenoid of diameter 4 cm, length 50 cm consists of 2000 turns. Calculate its self inductance

Answer 1

Given Data: Length AB = 200m = 2R; Time taken to finish one round = 40 sec.

Let the starting point be denoted as A in 140 sec or 2 min 20 sec number of rounds completed = 14040 = 3.514040 = 3.5. Distance traveled = 3.5x (2* r*r*R) = 3.5x2* rr*100= 2200 m approximately.

The displacement indicates to the change in position from starting point. Displacement = 200m.
