In which of the following the carriers of electric current are electrons only? A) SUPER CONDUCTOR B) A VOLTAIC CELL C) A SEMICONDUCTOR D) A HYDROGEN DISCHARGE TUBE

Text Solution

Verified by Experts

The correct Answer is:
C
By applying impulse-momentum theorem
`=|(m_(1)vec(v)_(1) + m_(2)vec(v)_(2)) - (m_(1)vec(v)_(1) + m_(2)vec(v)_(2))|`
`= |(m_(1) + m_(2)) vec(g) (2L_(0))| - 2(m_(1) + m_(2)) g t_(0)`
