Answer:
Electrical force, F = 90 N
Explanation:
It is given that,
Charge on sphere 1,
Charge on sphere 2,
Distance between two spheres, d = 6 cm = 0.06 m
Let F is the electrical force between them. It is given by the formula of electric force which is directly proportional to the product of charges and inversely proportional to the square of distance between them such that,
F = 90 N
So, the electrical force between them is 90 N. Hence, this is the required solution.
