To find the charge on the oil drop suspended in a uniform electric field, we can follow these steps: ### Step 1: Understand the forces acting on the oil drop The oil drop is in equilibrium, meaning the upward electric force is equal to the downward gravitational force. The forces can be described as: - Weight (mg) acting downwards - Electric force (qE) acting upwards ### Step 2: Write the equation for equilibrium ...
