A car is negotiating a curved road of radius R. The road is banked at angle . The coefficient of friction between the tyres of the car and the road is . The maximum safe velocity on this road is,

A.

A car is negotiating a curved road of radius R. The road is banked at angle  and the coefficient of friction between the tyres of car and the road is .
The given situation is illustrated as:

In the case of vertical equilibrium,

N cos  = mg + f1 sin
mg = N cos     ... (i)
In the case of horizontal equilibrium,

... (ii)
Dividing Eqns. (i) and (ii), we get

When the branches of an apple tree are shaken, the apples fall down. Why?

The apple fall from an apple tree when it shaken because of inertia of rest. Apple is in a state of rest and when the tree is suddenly shaken, apples still tends to remain in it's same state of rest whereas branches move.

So, the apples fall down.
