- Q2If you wanted to know the magnitude of the electric force on the test charge, what equation would you need?F=maF=-kxFe=kq1q2/r^2Fg=Gm1m2/r^2120s112.39.c.5.c
- Q3Which of the following is the best description of the (direction of the) net force on the charge once it is released?LeftZeroRightUp120s112.39.c.5.c
- Q4Coulomb’s law provides an equation to solve for the electric force between two charged particles, but here there are 3 particles total. How would you calculate the total electric force on the test charge at point P?Can't be calculated.Calculate the force between the test charge and the left particle.Calculate the force between the test charge and the right particleCalculate the force between the test charge and the left and right particles individually, and then add those two forces to get the net force.120s112.39.c.5.c
- Q5Calculate the magnitude of the electric force on the test charge if it has a charge of 1C, the particle on the left has a charge of 2C, the particle on the right has a charge of -2C, and the distance between the test charge and each particle is 0.5m. For now let's assume k=1 to keep it simple.16N left8N right8N left16N right120s112.39.c.5.c
