Question

Objects A and B are both positively charged. Both have a mass of 350 g, but A has twice the charge of B. When A and B are placed 15 cm apart, B experiences an electric force of 0.40 N What is the charge on A? Express your answer with the appropriate units. $q_A = 1500.4$ nC Incorrect; Try Again; 3 attempts remaining Part B If the objects are released, what is the initial acceleration of A? Express your answer with the appropriate units. $a = 1.33 \frac{m}{s^2}$ Incorrect; Try Again; 4 attempts remaining

Step 1

We are given that object A has twice the charge of object B. Let's represent the charge on object B as qB. Therefore, the charge on object A would be 2qB. Show more…
