How many electrons would have to be removed from a coin to leave it with a charge of +1.5 × 10^-5 c?

leave out with a charge of

Explanation:

We have given total charge

We know that charge on one electron =

We have to find the total number of electron in total charge

So , here q is total charge, n is number of electron and e is charge on one electron

So

So leave out with a charge of

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
