Question 4 (1 point) A spinning disc has a moment of inertia of 1.5 kgm and is spinning at a rate of 14 rad/s. If a 0.5 kg blob of clay is dropped on it 1.5 m from the
center, what is the new angular speed?

what is the question because that is not a question.

it doesn't. it was imagined up in the middle ages.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
