Asquare loop of wire with sides of length l and carrying a conventional current i lies in the yz-plane with its center at the origin. a. what is the magnitude of the magnetic field due to this loop at a location x on the x-axis?
b. what is the approximate equation for the magnitude of the magnetic field at a location x that is much greater than l , in terms of the magnetic moment of the loop?
c. is the result of part (b) consistent with our previously derived result for the magnetic field of a magnetic dipole?
provide explaination.

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n → ∞ n (9.8)(45−3 xi) i = 1 δx express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
