The constant k in Coulomb’s law depends on

A

Nature of medium

B

System of units

C

Intensity of charge

D

Both (1) and (2)

Answer

Nature of medium

Explanation

Solution

: The value of k=14πε0k = \frac{1}{4\pi\varepsilon_{0}}

Where ε0\varepsilon_{0}is permittivity of free space

=8.854×10−12C2N−1m−2= 8.854 \times 10^{- 12}C^{2}N^{- 1}m^{- 2}
