Apositive charge q moves with velocity v in the z direction through a magnetic field whose vector is in the x direction.
if the charge is negative and it moves in the negative-z direction, the force on the charge will be:
1.reversed
2.unchanged
3.zero
4.increased

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
