    How Does a Charged Particle Behave in a Magnetic Field?

    Usually since we are dealing with one particle, the place with the highest potential has the highest electrostatic potential energy, while in areas of lower potential, more work is done on them and therefore have more kinetic energy. Makes sense?

    What is the centripetal force acting on a truck going around a circular path?

    speed refers to the magnitude of the velocity. SInce the problem requires you to find the MAGNITUDE of centripedal acceleration, the speed would be fine.

    Water pressure in a tank problem

    Apparently You had to count in air pressure (10^5 pascals) since it can still exert pressure on the bottom...Is it correct with that added?
