If the force experienced by a positively charged balloon is 2.7 newtons and the electric field strength is 7.8 × 105 newtons/coulomb, what is the magnitude of the charge on the balloon?

Explanation:

The electric force experienced by a charged object when immersed in an electric field is given by

where

F is the force

q is the charge

E is the electric field

The direction of the force is:

- The same as the field if the charge is positive

- Opposite to the field if the charge is negative

In this problem we have:

F = 2.7 N is the force experienced by the balloon

is the magnitude  of the electric field

Solving for q, we find the magnitude of the charge on the balloon:

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
