4. Kim pushes a lawn mower across a lawn by applying a force of 95 N along the handle that makes an angle of 60° to the horizontal,
a. What are the horizontal and vertical components of this force?
b. The handle is lowered so it makes an angle of 30° with the horizontal, Now what
are the horizontal and vertical components of the force?

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.)
