1. In the figure, if Q-30 μC, q=5.0 μC, and d = 30 cm, what is the magnitude of the electrostatic force on q? ad 20 2. A particle (m = 50 g, q = 5.0 μC) is released from rest when it is 50 cm from a second particle (Q-20 µμC). Determine the magnitude of the initial acceleration of the 50-g particle. 3. If a 3.0 mm, b = 4.0 mm, Q₁ = 60 nC, Q₂ = 80 nC, and q = 24 nC in the figure, what is the magnitude of the total electric force on q? O
