Aircraft sometimes acquire small static charges. suppose a supersonic jet has a charge of +0.05 c and flies due west at a speed of 660 m/s over a location where the 8.00 x 10-5 t magnetic field points straight up (vertically out of the earth or out of the paper). what are the direction and the magnitude of the magnetic force on the plane?
a. 2.64 x 10-4 n to the west (direction of v)
b. 2.64 x 10-3 n straight up (direction of b)
c. 2.64 x 10-3 n to the north
d. 2.64 x 10-4 n to the south
discuss whether the value obtained implies this is a significant or negligible effect.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
