Question

Two identical slugs of copper are each formed into a wire. Wire One has resistance R_1 is twice as long as Wire Two, which has resistance R_2. How is R_1 related to R_2? R_1 = R_2. R_1 = 2R_2 R_1 = 4R_2. R_1 = 8R_2. R_1 = 16R_2. Explain your response in the space provided. The graphs shows the electrical potential in a region that a test charge moves through. The test charge travels in a straight line. It has a mass of 250pg and4 net charge of 10 pC. What is the magnitude and direction of the electric field at x = 5.5 m? The test charge is released at x = 3.5 m. How fast and in what direction is it moving after undergoing a 50 cm displacement?

Explanation / Answer

R = rho *L/A

rho is resistivity of wire

L is length of wire

A is cross section of wire

R1= rho*2L/(A/2) { if length become double then area become half if the material is same}

R1 = 4R2

option C is correct
