Homework Statement The 300 μF capacitor is initially charged to 100 V, the 1200 μF capacitor is uncharged, and the switches are both open. So the picture is two capapcitor in either side of the circuit. There is a inductor 5.3 H in the middle wire that divide the switches in eaither side of...

Never mind, I've found the right answer...We actually don't need Tension to solve it Thanks for great hint

So basically, there will be tension, gravity and electric field act on it and gravity and electric field will have x,y component but how can we figure out Tension? So saying the ball doesn't move we can set everything =0 but we don't have tension

An electric field causes the 5.0 g point charge to hang at a 20 angle. What is the charge of the ball I don't have the figure but it looks like a simple pendulum hanging at the angle of 20 degree Homework Statement E= 100,000 N/C m of the ball = 5g Angle =20 degree e0= 8.85*10^12...
