It's possible for it to stay on the boulder because the normal force balances it's weight. also because static friction acts on the boulder up to it's limiting friction even if it were on an attempt to move as a result of air resistance. gravitational forces act upon it by mainly affecting it it's weight. as altitude increases, it's weight decreases since gravity varies from a height to another.

A solid sphere of radius A has auniform magnatization

worty [1.4K]

Answers and Explanation:

The step by step explanation is clearly screenshot in the two attachments below for easy understanding.

NOTE:

A uniform charged solid sphere of radius R carries a total charge Q, it therefore has its charge density as Q/(4/3ΠR³). And to find magnetic moment of a sphere, the sphere has to be divided into infinitesimal charges.

Magnetic Dipole Moment of the sphere would be given as 1/5QwR²z
