A certain pair of slits are separated by a distance d. Monochromatic coherent light falls on this pair of slits and the interference pattern is observed on a screen. The separation distance between adjacent bright fringes near the center of that interference pattern on the screen is found to be 2.0 mm. Then the slits are replaced by another pair of slits; these slits are separated by a distance one-half that of the original pair. The interference pattern is again observed. What is the new separation distance between adjacent bright fringes

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
