JEE Main 2025 Physics question
An electron is released from rest near an infinite non-conducting sheet of uniform charge density ''. The rate of change of de-Broglie wave length associated with the electron varies inversely as power of time. The numerical value of n is .
Answer: 2
Solution
F = qE = constant, so p = (qσ/2ε₀)t. , , so n=2.
