Two spherical bodies, each of mass 50 kg, are placed at a separation of 20 cm. Equal charges are placed on the bodies and it is found that the force of Coulomb repulsion equals the gravitational attraction in magnitude. Find the magnitude of the charge placed on either body.
Answers
The magnitude of the charge placed on either body is, .
Explanation:
Step 1:
The given data in questions :
Mass = m₁ = m₂ = 50 kg.
The distance ( r) = 20 cm
Converting centimeter to meter :
Step 2:
Based on the question,
Here,
and
Where,
Step 3:
Squaring on both sides, we get
Thus, the magnitude of charge is, 4.3×.
