Electrostatic force between two identical charges placed in vacuum at distance of is . A slab of width and dielectric constant is inserted between these two charges, then the force between the charges is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Force between the two charges when it is placed in vacuum and distance between them is r is F=14πε0q1q2r2. Now, the force when a dielectric k is inserted between these two charges is F=14πε0q1q2kr'2. On comparing the dielectric force with the vacuum force we…
