The force exerted by a magnetic field on a wire having length L and current I is perpendicular to the wire and given as |F|=IL|B| . An experimetal plot shows (vecF) as function of L . The plot is a straightline with a slope S=(10 pm1 xx 10^(-5) AT. The current in the wire is (15 pm 1) mA. The percentage error B is approximately 4x . find the value of x. (All quantities are in SI unit) |
