NDA General Science Physics Questions Part 3

Two metallic wires A and B are made using copper. The radius of wire A is r while its length is l. A dc voltage V is applied across the wire A , causing power dissipation P. The radius of wire B is 2r and its length is 2l and the same dc voltage V is applied across it causing power dissipation P‌1 . Which one of the following is the correct relationship between P and P‌1 ?
