12. The space between the positive and negative plates of a parallel plate capacitor is d, each plate has a length L, see sketch below. The electric field between the plates of the capacitor is held constant at E. An electron enters the capacitor at d/2, traveling along the x-direction with velocity vox What is the minimum velocity that would allow the electron to exit the capacitor without striking any of the plates? (Assume the electrostatic force is the only force present.)

PLease answer this within 30 mins ! I will upvote !

. Analyze the screenshot below to estimate how many electrons are on the balloons. Solve for the number of electrons on q2 if m1 = m2 = 15 grams, the system is in static equilibrium, q1 = q2, L = 2 m, and r = 18 cm.

Two parallel plates are connected to a 100V battery and create a uniform electric field of E 1X10² ", the two plates are 5cm apart. If a proton is released from rest on the positive plate what is the velocity when it reaches the negatively charged plate, and how long does it take to reach the plate? Use any means necessary to solve, i.e. kinematic equations, forces, energy, or all the above. Draw a force diagram of the electric field on the proton, assuming the effect of gravity can be negated. proton- 5cm ++++

A parallel-plate capacitor has a charge Q and plate separation d, as shown below. We assume that the size of plates is much larger than the separation d. Each particle is initially at rest and then released, allowing it to accelerate.  Assuming each particle has the same mass, rank the speeds of the particles when they impact the left plate. 1.

Your object has mass 39.3 kg, and youve separated the boxes of protons and electrons by a distance of 23 m. If you were to release the clump of protons from their box, how much acceleration would the clump of protons undergo due to its attraction to the clump of electrons in the other box?     A. 1.54E+24 m/s^2   B. 3.07E+24 m/s^2   C. 6.14E+24 m/s^2   D. 1.23E+25 m/s^2
