An air-core solenoid having a diameter of 4cm and of length 60cm is wound with 4000 turns. find the inductance of the solenoid. what will be the inductance of the solenoid if it has an iron core of relative permeability of 400?

Solution: Length(l)=60cm=0.6m Radius (r)=$\frac{4}{2}$cm= $2 \times {10^{ - 2}}$m ${\mu _r}$=400 Inductance of solenoid , $\begin{array}{l}L = {\mu…

A 0.15 kg glider is moving to the right on a frictionless horizontal air track with a speed of 0.80ms-1. It has a head on collision with a 0.300 kg glider that is moving to the left with a speed of 2.2ms-1. Find the final velocity (magnitude and direction) of each glider if the collision is elastic.

Solution:
