Answer:
15 Joules
Explanation:
work = charge x potential difference
= 10 x 1.5
= 15
Answer:
126 mWb
Explanation:
Given that:
length (L) = 50 cm = 0.5 m, radius (r) = 5 cm = 0.05 m, current (I) = 10 A, number of turns (N) = 800 turns.
We assume that the magnetic field in the solenoid is constant.
The magnetic flux is given as:

Displacement is zero. That’s because she ended up where she started.
