Two astronauts are working on the lunar surface to install a new telescope. The acceleration due to gravity on the moon is only 1.64 m/s2. One astronaut tosses a wrench to the other astronaut, but the speed of throw is excessive and the wrench goes over her colleague's head. Which of the following occurs when the wrench is at the highest point of its trajectory?
Its velocity and acceleration are both nonzero.
Its velocity and acceleration are both zero.
Its velocity is zero but its acceleration is nonzero.
Its velocity is zero but its acceleration is zero.
Insufficient information is given to choose between any of the previous choices.

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
