Apoint charge is placed 100 m from a 6 µc charge generating an electric field. what is the strength of the electric field on the point charge? (round to the nearest whole number.)

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.
