Question
Physics Question on electrostatic potential and capacitance
A positively charged particle is released from rest in a uniform electric field. The electric potential energy of the charge
A
remains a constant because the electric field is uniform
B
increases because the charge moves along the electric field
C
decreases because the charge moves along the electric field
D
decreases because the charge moves opposite to the electric field
Answer
decreases because the charge moves along the electric field
Explanation
Solution
In a uniform electric field, when a positively charged particle is released from rest, it moves along the electric field, that is from higher potential to lower potential. Therefore, electric potential energy of charge decreases
