Ques 1.   Find  the radius of  5th orbit of  a Li+2  ion.  Radius of first orbit of  H atom is 0.529Å.

Ans.      4.408 Å

Ques 2.   What is the moment of  inertia of  a rod about the axis passing through its one end?

Ques 3.   Assertion: For  a projectile motion, range is maximum at q = 45°.

               Reason:  For  range to be maximum, sin2q needs to be 1.

Ans. Both are true

Ques 4.   Which  graph   represents  the  relationship    between  conductivity    and  temperature   for    a semiconductor?

For semiconductor on increasing temperature, n increase & t decreases. But effect of n is dominating, So graph will be
