1. Two wires are made of same material. The length of the first wire is half of the second
wire and its diameter is double that of the second wire. If equal loads are applied on both
the wires find the ratio of increase in their lengths.​

c the car's velocity increases constantly over time.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

i think the answer is a, hope this : )
