Answer:
The magnitude of electrostatic force on each charge is quarter of the magnitude of initial electrostatic force. ( ¹/₄ F)
Explanation:
The electrostatic force between two charges is given by Coulomb's law;
where;
Q₁ and Q₂ are the magnitude of the charges
r is the distance between the charges
k is Coulomb's constant
Since the charges are identical;
Q₁ = Q
Q₂ = Q
the electrostatic force experienced by each charge is given by;
When each of the spheres has lost half of its initial charge;
Q₁ = Q/2
Q₂ = Q/2
Therefore, the magnitude of electrostatic force on each charge is quarter of the magnitude of initial electrostatic force.
Answer:
4.5m
Explanation:
Distance is the total length of path traveled or covered by a body.
So distance is a scalar quantity, it only has magnitude but no direction.
Therefore:
Total distance = 3 m + (3)
So;
3 + 1.5 = 4.5m
Total distance covered 4.5m by the body.
