The force F is directly proportional to the product of charges q and Q and inversely proportional to the square of the distance R between the two charges F is 40newton R is 16m q is 20c Q is

The charge Q is 512 c.

Step-by-step explanation:

Step 1:

The equation is , where q and Q are the charges, R is the distance between the charges, and F is the force between the charges.

From the question, we have;

F = 40 Newton, R = 16 m and q = 20 C.

We need to calculate Q.

Step 2:

By substituting the values of F, R, and q in the equation, we get

.

We cross multiply to solve Q.

So Q = 512 C.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
