Please explain the reasoning for 2 and 3.

1. Consider two small plastic balls: a large ball with a charge of 2.5 x 10-C and a small ball with a charge of 1 x 10 C (treat them as "point charges.") If the balls are held in place 2.1m away from one another, what is the magnitude of the electrical force that each ball exerts on the other? A. 0.79N B. 115N C. 1.9N D. 2.4N E. 0.51N 2. Consider the balls in the previous question. Which ball feels the greatest force from the other? A. The small ball is feeling a greater force B. The large ball is feeling a greater force C. Both balls are feeling equal forces D. It cannot be determined without more information 3. Once again, consider the balls described above. If there are no other charged objects present, which of the following electric fields has the least magnitude? A. The electric field felt by the small ball (which is created by the large ball) B. "The electric field felt by the large ball (which is created by the small ball) C. Both of these electric fields are equal in strength D. It cannot be determined without more information 4. Yesterday, I was using a capacitor to store 48 /C of charge with a potential difference between the plates of 2V. Today, without physically changing the capacitor, I'm using it for a different purpose and it is currently storing 8. uC of charge. What is the capacitance of this capacitor today? A. 2 HF B. C. 8 HF D. 12 HALF E. 24 LLE
