Answer 1

The electric field strength (E) due to a point charge (or a uniformly charged sphere, which behaves like a point charge for points outside the sphere) is inversely proportional to the square of the distance (r) from the charge. This relationship is given by:E ∝ 1/r²This means that if we double the distance, the electric field strength becomes one-fourth. If we halve the distance, the electric field strength becomes four times larger.We can set up a proportion:E₁/E₂ = r₂²/r₁²Where:* E₁ is the initial electric field strength (100 N/C)* r₁ is the initial distance (1.0 m)* E₂ is the final electric field strength (50 N/C)* r₂ is the final distance (what we want to find)Plugging in the values:100 N/C / 50 N/C = r₂² / (1.0 m)²2 = r₂² / 1 m²r₂² = 2 m²r₂ = √2 m ≈ 1.4 mSo the answer is (b) 1.4 m
