Answer:
Part b)
Explanation:
magnetic field due to external source is given as
area of the loop is given as
Now we have
now we need to find the time at which voltage is 0.1 Volts so we have
Part b)
If magnetic field is inclined at an angle of 30 degree with the normal of the loop then
now we know that induced EMF is given as
Answer:
a)
b)
c) Therefore it is a nonconservative force
Explanation:
Distance traveled in one complete circular trip against friction
The force of friction is
The work of friction is the force of friction in the distance so
a).
b).
c).
Since the circle returns to its initial position in both cases and the work done by the friction force different in both cases, so the friction force does depend on the path;
