The magnetic field near the surface of a neutron star has a magnitude of 1.00 x 108 T. Evaluate the acceleration of an electron near the star moving at 1.08 x 107 m/s if both v and B are in the same plane, with B directed to the right and v directed 31.1o above B.
Compute the magnitude of the acceleration.
A 1.55 kilogram block slides across a rough surface such that it slows down with an acceleration of1.10 m/s2. Obtain coefficient of kinetic friction between block and surface
