Objects one and to attract each other with an electrostatic force of 36 units if the charge of object one is halved then the new electrostatic force will be

The new electrostatic force will be half the initial force.

Explanation:

Let is call the charges of the two objects and , if the separation between them is , then the electrostatic force between them will be

where is the coulomb's constant.

If let's say the charge is halved, then it becomes  . The electrostatic force then becomes

Thus, the new electrostatic force will be half the initial force.

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

ill do it for 100, also this isnt 80 its 40
