The number of lines of force originating from a point charge of 2 8.85 10⁻⁹ C in a medium of dielectric constant 10 is ( ₀ = 8.85 10⁻¹² SI unit)

Step-by-step solution

The number of lines of force originating from a charge q in a medium of dielectric constant K is given by Gauss's Law as = q K ₀ . Given: q = 2 8.85 10⁻⁹ C K = 10 ₀ = 8.85 10⁻¹² SI unit Substituting the values: = 2 8.85 10⁻⁹ 10 8.85 10⁻¹² = 2 10⁻⁹ 10⁻¹¹ = 200 Answer: 200
