Objects 1 and 2 attract each other with a electrostatic force of 18.0 units. If the distance separating Objects 1 and 2 is
doubled, then the new electrostatic force will be units.

Suppose you have three polarizing filters, with the second at an angle of 42∘ to the first and the third at an angle of 90∘ to the first. by what perfect will the original intensity of unpolarized light be reduced to after passing through all three filters?
