Question

If the force experienced by a positively charged balloon is
2.7 newtons and the electric field strength is 7.8 × 10¢ newtons/coulomb, what is the magnitude of the charge on the balloon? A. 3.5 x 10-4 B. 4.2 x 10 5 C. 3.5x 10 4 D. 7.8 x 10 5 please help me

Answer 1

you can get the magnitude of the charge \(q\) using the relation:
\[F=qE\]
where \(F\) is the force experienced by the charged balloon and \(E\) the magnitude of the elctric field
