A student builds a simple circuit with a single resistor of resistance 2R2R2, R and current III, and measures an electric potential difference of \Delta V_1ΔV 1 ​ delta, V, start subscript, 1, end subscript across the resistor. Then, the student decreases the current through the circuit to \dfrac{I}{2} 2 I ​ start fraction, I, divided by, 2, end fraction.

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.)

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
