Two long, parallel wires, each having a mass per unit length of 37.5 g/m, are supported in a horizontal plane by strings ℓ = 6.15 cm long. when both wires carry the same current i, the wires repel each other so that the angle between the supporting strings is θ = 16.2°.

explanation:

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
