Question 1 of 5 - / 10 E View Policies Show Attempt History Current Attempt in Progress Particle 1 of 30 nC and particle 2 of - 40 nC are held fixed on an x axis, at the origin and at x = 72 cm, respectively. Particle 3 of 42 UC is released from rest at x = 28 cm. If the initial acceleration of particle 3 has a magnitude of 100 km/s?, what is its mass? Step 1 Create the free-body diagram for particle 3. Use the checkboxes to select the correct vectors as instructed above. Move the vectors to the correct starting points and orient them in the correct direction as instructed. VF F1 Key to Force Labels F1 = Force from particle 1 V F 2 20 F2 = Force from particle 2 OF3 V F 3 F3 = Force from particle 3 Draw free-body diagram here Point the acceleration vector in the correct direction . ... .. ... ........". eTextbook and Media Attempts: 0 of 2 used Submit
