[a] Two foam blocks, each with a charge of 19 micro coulombs (1 C = 10-6 C), are both held in place 19 cm apart

 

[a] Two foam blocks, each with a charge of 19 micro coulombs (1 µC = 10-6 C), are both held in place 19 cm apart in the east-west direction. A foam ball with a charge 49 µC is placed 55 cm north of the foam block on the west side. Then, the ball is released, and it moves as a result of the electrostatic force produced in this system. make a diagram of this system, and label the relevant objects, quantities, and force vectors before the ball is released.

 [b] What is the strength of the electric field (magnitude and direction) exerted on the ball by the closer block? 

 [c] What is the net electrostatic force (magnitude and direction) experienced by the foam ball? 

[d] If the foam ball has a mass of 0.025 kg, what would be its velocity 487 milliseconds after the ball is released? Is this a physically realistic system, or are your answers too big or too small to make sense? Explain your reasoning in a paragraph.
