In a region where there is a vertical magnetic field of 1.96 times 10^-2 T, a ring of radius 1.02 cm is flipped in the air as one would flip a coin, so that it begins rotating about a horizontal axis at the rate of 54.0 rev/s. (a) Find the maximum instantaneous emf induced in the ring if the ring has a resistance of 1.10 times 10^-4 Ohm. Find the maximum current if the ring has a resistance of 1.10 times 10^-4 Ohm.
(b) What effect does the magnetic field have on the rate of rotation?

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

seeing the graph would

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
