Consider a spot that is located midway between two identical point charges. Which one of the following statements concerning the electric field and the electric potential at this spot is true? (a) The electric field is zero, but the electric potential is not zero. (b) The electric field is not zero, but the electric potential is zero. (c) Both the electric field and the electric potential are zero. (d) Neither the electric field nor the electric potential is zero.
Physics 105 Week 3 Notes By Lauren Faris Chapter 2: 1D Kinematics (Continued) The position of a particle can be described as a position vector. Average velocity is the displacement divided by the time interval. Instantaneous velocity is the instantaneous rate of change of position vector with respect to time. It is always tangent to its path. Acceleration describes how the velocity changes. Average acceleration is the change in velocity divided by the time interval. Deltav = v – 2 1 A x dv /xdt, a =ydv / yt, a =zdv / zt Velocity and acceleration vectors for a particle moving through a point P on a curved path with increasing speed. A particle moves in a vertical plane with only acceleration equal to the free
