A8 µc charge q1 and a 10 µc charge q2 are 0.05 m from the x-axis. a 6 µc charge q3 is 0.12 m from the y-axis. the distances d13 and d23 are 0.13 m. find the magnitude and direction of the resulting vector r. round to one decimal place.

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge, at the position of the second charge, change if the second charge is doubled? a. the field does not change b. the field strength decreases by half. c. the field strength doubles d. the field strength quadruples

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)

What is the moment of inertia i of this assembly about the axis through which it is pivoted? express the moment of inertia in terms of mr
