A -3.5 uC charge experiences a 13N i hat electric force in a certain electric field.What would the force be for a proton experience in the same field?

I amd doing this 13/-3.5=-3.7

then multiplying 1.6*10^19

where did i go wrong

To determine the force experienced by a proton in the same electric field, you need to use the formula:

F = qE

where F is the force, q is the charge, and E is the electric field.

In this case, the charge of a proton is 1.6 x 10^-19 C, and the electric field is 13 N i hat.

So, you can calculate the force experienced by a proton as follows:

F = (1.6 x 10^-19 C) * (13 N i hat)

The direction of the force experienced by the proton can be determined from the direction of the electric field, which is given as i hat.

Therefore, you don't need to perform any division by -3.5 or any other calculations. Simply multiply the charge of a proton with the given electric field.
