Respuesta :
Force becomes 1/4th
Explanation:
- Force between two positively charged particles is given by the equation
F = k×q1×q2/r² So, force is inversely proportional to square of r.
Here, k is a constant, q1 and q2 are the charges which are equal and r is the distance between them.
- So if the distance is doubled, r becomes 2r and r² becomes (2r)² = 4r²
- Force, F then becomes 1/4th of the initial force.
