g Suppose that 3 J of work is needed to stretch a spring from its natural length of 36 cm to a length of 50 cm. (a) How much work is needed to stretch the spring from 40 cm to 42 cm? (Round your answer to two decimal places.) J (b) How far beyond its natural length will a force of 10 N keep the spring stretched? (Round your answer one decimal place.) cm

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.
