A positive point charge q of mass m is released from rest from the positive plate of a capacitor. Determine the following as a function of the electric field E: a) x (distance from the + plate) b) Vf (velocity before hitting the negative plate a distance d away) c) the kinetic energy of the charge just before hitting the negative plate.
Two situations are shown below. In situation (1), a
negative charge (A) is placed near a single positive charge. In
situation (2), the same negative charge (A) is placed the same
distance away the positive end of a dipole.
Please explain your answer.

P2. An electron is released from rest at a position 3.5 cm from a charge q. The electron experiences an acceleration of 6.8 × 1012 m/s away from g. Calculate q
Q1.4 Consider two positive point charges Q at a distance 2R from each other. Sketch the electric field lines including their direction. Q1.5 In Q1.4, calculate electric fields (i) at a distance R to the left of the left charge, (ii) at a distance R to the right of the right charge, and (iii) at the mid-point between the two charges. Assume Q = 1C and R = 1m. Q1.6 Same question as in Q1.5 but make the left charge...
The figure shows a test charge q between the two positive charges. Find the force (in newtons) on the test charge for q=4 μC. Give a positive answer if the force is to the right and a negative answer if the force is to the left.For the previous question, find the electric field (in newtons/coulomb) at the position of the test charge. Again, supply a positive value if the electric field points to the right and a negative value if...
Can someone help me with this? Thanks.
An electron is released from rest at the negative plate of a parallel plate capacitor. The charge per unit area on each plate is o are separated by a distance of 1.7 × 10-2 m. How fast is the electron moving just before it reaches the positive plate? 2.5 x 107 c/m2, and the plates Number Units the tolerance is +/-2%
2 u C 30C 2 cm 3 cm The figure shows a test charge q between the two positive charges. Find the force (in newtons) on the test charge for q = 2 uС. Give a positive answer if the force is to the right and a negative answer if the force is to the left. (Reminder: NEVER include units with ANY submission to a numerical question.) For the previous question, find the electric field (in newtons/coulomb) at the position...

A negative point charge is fixed at the origin. A positive charge q is placed at point P, initially at rest. After it is released and allowed to move freely, it passes through point R. Which of the following is true about the charge q: A. Its kinetic energy is larger at R than at P, and its potential energy is also larger at R than at P B. Its kinetic energy is larger at R than at P, but...
