What is the angular acceleration of the pencil when it makes an angle of 10.0 degrees with the vertical? express your answer numerically in radians per second squared to three significant figures?

Explanation:

As we know by Newton's law

here torque is due to the weight of the pencil which will act on the center of the pencil

so here we will have

now we know that the moment of inertia of the pencil is given as

now we will have

for 10 degree angle we have

coil wire, increase current, put iron inside the coil

answer: b.
