Question

Calculate electric force a 0.020-kg balloon is charged by rubbing and then stuck to the ceiling. if the strength of earth's gravity on an object is 9.8 n/kg, how large is the electric force on the balloon?

Answer 1

The electric force on the balloon is 9.60 × 10^-14 N.

Step-by-step explanation:

The electric force on the balloon can be calculated using the formula F = qE, where F is the electric force, q is the charge on the balloon, and E is the electric field strength. In this case, the charge on the balloon is 3.20 × 10^-19 C and the electric field strength is 3.00 × 10^5 N/C. Therefore, the electric force on the balloon is:

F = (3.20 × 10^-19 C)(3.00 × 10^5 N/C) = 9.60 × 10^-14 N
