Q2. In a semiconductor, the forbidden energy gap between the valance band and the conduction band is of the order of
Answer : Option B
Explaination / Solution:
The material which has electrical conductivity between that of a conductor and an insulator is called as semiconductor. Silicon, germanium and graphite are some examples of semiconductors.
In semiconductors, the forbidden gap between valence band and conduction band is very small. It has a forbidden gap of about 1 electron volt (eV).

Q8. For uniformly accelerated motion velocity at time t is given by
Answer : Option A
Explaination / Solution:
Consider a particle moving along a straight line with uniform acceleration 'a'. At t = 0, let the particle be at A and be its initial velocity and when t = t, v be its final velocity.
Acceleration =
