Static friction acts in the opposite direction to the acceleration.
Kinetic friction acts in the opposite direction to the velocity.
Answer:
The magnitude of the voltage is
and the direction of the current is clockwise.
Explanation:
Given that,
Number of turns = 9
Magnetic field = 0.5 T
Diameter = 3 cm
Time t = 0.14 s
We need to calculate the flux
Using formula of flux

Put the value into the formula


We need to calculate the emf
Using formula of emf




Negative sign shows the direction of current.
Hence, The magnitude of the voltage is
and the direction of the current is clockwise.
Using the Definition of Work, we have:
