Consider an XY coordinate plane. Wire A is placed along the y-axis at x=0 and wire B is placed parallel to wire A at x= 0.240 m. Wire A has a current of 2.80 A in the positive y-direction and wire B has a current of 4.10 A in the positive y-direction. Find the magnitude of the magnetic field at x=0.380 m. Give your answer in micro-tesla (?T).
An electric field does 11.10 MeV of work in moving a very small charged particle from point a to point b through a potential difference of -2.22 MV
Compute the ground state energy and wavefunction

A 15.1 mass fastened to the end of a steel wire with an unstretched length of 0.650 is whirled in a vertical circle with angular velocity 2.00 at the bottom of the circle. The cross-sectional area of the wire is 1.20×10?2 . Calculate the elongatio..
Three pendulums with strings of the same length and bobs of the same mass are pulled out to angles q1, q2 and q3 correspondingly and released. The approximation sin q = q holds for all three angles, with q3 > q2 > q1. How do angular frequencies of th..
A uniform plank of length 4.30 m and weight 226 N rests horizontally on two supports, with 1.10 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs 437 N walk on overhanging part of the plank be..
