Good afternoon! I'm stumped with this question here. Q: An electron starts from rest 32.5 cm from a fixed point charge with Q=-0.125μC. How fast will the electron be moving when it is very far away? I got an answer of 5.54 * 10^-16 J, but apparently it is
Two 2.3-cm-diameter-disks spaced 1.8 mm apart form a parallel-plate capacitor. The electric field between the disks is 4.6×105 V/m. A. What is the voltage across the capacitor = 830 V (solved) B. How much charge is on each disk? (Find Q1 and Q2) C. An
An electron with speed 2.35×107m/s is traveling parallel to a uniform electric field of magnitude 1.16×104N/C . How far will the electron travel before it stops? A=0.135m How much time will elapse before it returns to its starting point? I solved for the
An electron (mass m = 9.11 * 10^-31 kg) is accelerated in a uniform field vector E ( E =1.45 * 10^4 N/C) between two parallel charged plates. The seperation of the plates is 1.10 cm. The electron is accelerated from rest near the negative plate and passes
Rick deposits $1,000 into an investment account which earns 4% annually. Sally loans $1,000 to a friend, and the friend agrees to pay her $50 each year, and will return the $1,000 after 10 years. Determine the amount of money each person has after 10
A projectile is fired from the surface of the Earth with a speed of 200 meters per second at an angle of 30° above the horizontal. If the ground is level, what is the maximum height reached by the projectile? (A) 5 m (B) 10 m (C) 500 m (D) 1,000 m (E)
A constant force is exerted for a short time interval on a cart that is initially at rest on an air track. This force gives the cart a certain final speed. Suppose we repeat the experiment but, instead of starting from rest, the cart is already moving with
an electron enters the region of a uniform,electric field with 3X10^6m/s and e=200 N/C . the horizontal length of the plates is 0.100m. a) find the acceleration of the electron while it is in the electric field . b) if the electron enters the field at time
A body at rest is given an initial uniform acceleration of 8m/s2 for 30s after which the acceleration is reduced to 5m/s2 for the next twenty seconds. The body maintains the speed attained for 60s, after which it is brought to rest in 20s. 1. Draw the
Compare the electric force holding the electron in orbit (r=0.53Ã—10âˆ’10m) around the proton nucleus of the hydrogen atom, with the gravitational force between the same electron and proton. What is the ratio of these two forces?
A CAR STARTS FROM REST AT A CHECKPOINT A AND COMES TO REST AT THE NEXT CHECKPOINT B,6KM AWAY IN 3 MINUTES.IT HAS FIRST A UNIFORM ACCELERATION FOR 40 SECONDS,THEN A CONSTANT SPEED AND IS BROUGHT TO REST WITH A UNIFORM RETARDATION AFTER 20 SECONDS.SKETCH A
