MCQ
An $\alpha $-particle is accelerated through a potential difference of $200\,V$. The increase in its kinetic energy is.......$eV$
- A$100$
- B$200$
- ✓$400$
- D$800$
✓
Answer
Correct option: C.
$400$
c
(c) $KE = QV\, \Rightarrow KE = (2e)\,200\,V = 400\,eV$
(c) $KE = QV\, \Rightarrow KE = (2e)\,200\,V = 400\,eV$
