a. Two identical positive point charges Q are initially spaced a distance d apart. If they are released from rest, how fast will they be moving when they are very far away from each other? Assume they have identical masses m, and express your answer in terms of the given quantities and the Coulomb constant k. b. Evaluate the speed numerically if Q = 0.71 ?C, m = 1.13 mg, and d = 5.5 cm.
An electron is released from rest at a distance of 9 cm from a proton. How fast will the electron be moving when it is 3 cm from the proton?
(1 point) A proton collides with a Boron-11 nucleus (Bl). If the proton gets close enough (to within 7.91 fm), it will fuse with the Boron nucleus and produce three helium nuclei (3He“): Pł + B + 3He: (A) How fast would the proton need to be moving at an initial distance of 180 fm to get to 39.5 fm from the Boron nucleus? Assume the proton comes to rest when it reaches 39.5 fm. (B) If the proton has...
Two identical + 9.0 μC point charges are initially 5.0 cm from each other. If they are released at the same instant from rest, how fast will each be moving when they are very far away from each other? Assume they have identical masses of 3.0 mg .
A proton and an alpha particle are released from rest when they are 0.215 nm apart. The alpha particle (a helium nucleus) has essentially four times the mass and two times the charge of a proton. A.) Find the maximum speed of proton. B.) Find the maximum speed of alpha particle. C.) Find the maximum acceleration of proton.
Two identical +7.0 µC point charges are initially spaced 5.6 cm from each other. If they are released at the same instant from rest, how fast will they be moving when they are very far away from each other? Assume they have identical masses of 1.0 mg.
Please fully explain 4) A proton is to be accelerated from rest by using an accelerating voltage of 400 volts. a) How fast will the proton be going after the acceleration through 400 volts? b) Should the proton start out at a higher or lower voltage? c) If the proton is to be accelerated with twice the voltage (800 volts), will the final velocity of the 2.77x10' m/s higher proton be twice as large, less than twice as large, or...
