Okay, I have been up all night doing my physics and geometry homework (I hate geometry).
I can barely think... I need to sleep... But I have to wake up at 7am... so yeah heres my questions: 1. In a 15 volt potential, a particle has a potential energy of 0.67 Joules. What is the particles charge? 2. A +3.5 mC charged particle (m=1.2kg) is shot with an initial velocity of 198 m/sec towards a =2.1 mC stationary charge. If the particle starts out 1.6 meters from the stationary charge, how close will it come to the charge before turning around and moving away? 3. A proton (m=1.7X10^27kg, q=+1.6x10619C) is placed at the edge of the positive plate of a 3.5 x 10^6 F capacitor. If the capacitor holds 16 mC of the charge on its positive plate, how fast will the proton be moving when it reaches the negative plate of the capacitor? Thanks sooo much I really appreciate the help!!!
