A can of sardines is made to move along an x axis fromx1 = 0.22 m tox2 = 1.22 m by a force given byF = iF0exp(-0.36x), with x in meters andF0 = 4 N. (Here exp is the exponential function.) How much work is done on the can by the force?
The charge experiences a magnetic force of 7.41 10-3 N. A second charge q2 = 4.00 µC travels at an angle of 40.0° with respect to the same magnetic field and experiences a 1.80 10-3-N force. Identify the magnitude of the magnetic field and the ..
