Questions Related to neutral points

The primary origin of magnetism lies in the

properties of magnet magnetic field moving charges and magnetism magnetic effects of current and magnetism physics neutral points magnetic poles and magnetic compass

  1. atomic current and intrinsic spin of electrons.

  2. polar and non polar nature of molecules.

  3. pauli exclusion principle.

  4. electronegative nature of materials

Show answer
Correct Option: A
Explanation:

Atomic currents and intrinsic spins of electrons are responsible for origin of magnetism.

If we go inside a mine and drop a $104 lb$  iron ball and $1$ lb aluminum ball from the top of a high platform, neglecting air resistance.

  1. Both will reach the floor at the same time

  2. $1$ lb weight will reach the floor first

  3. $10$ lb weight will reach the floor first

  4. It is not possible to indicate which of the two will reach the floor first without further data

Show answer
Correct Option: A
Explanation:
In real life the one having less volume and more weight will reach first

but in ideal situation where viscosity of air is neglected both will hit ground at same time irrespective of their masses if dropped from the same height 

this is because the acceleration produced due to gravity does not depend on the body.
