The distance between two charges q1 = + 2 μC and q2
= + 6 μC is 15.0 cm.
Calculate the distance from charge q1
to the points on the line segment joining the two
charges where the electric field is zero.

True or false graphs must include scales that increase by the same amount

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
