In outer space, a ball with a mass of 0.25kg and charge +4/kC is shot from 5m towards a +0.5C charged ball with an initial velocity of 20 m/s. What is the closest the small ball will get to the large one's center?
A thin metal rod of mass 1.8 kg and length 0.9 m is at rest in outer space, near a space station (see figure below). A tiny meteorite with mass 0.06 kg traveling at a high speed of 250 m/s strikes the rod a distance 0.2 m from the center and bounces off with speed 60 m/s as shown in the diagram. The magnitudes of the initial and final angles to the x axis of the small mass's velocity are...
A positive charge q1=2*10^-9 C is held fixed at the origin. A small particle with mass m=.004 kg and a negative charge q2=-5*10^-9 C is placed on the x-axis at point A, which is at x=.5m. The particle is released from rest and moves along the x-axis towards the origin. What is the speed of the particle when it reaches point B, which is at x=.3 m? Answer is .00775 m/s Please show work on how to get here
A small plastic ball of mass
6.30 × 10-3 kg and charge +0.193C is suspended from an insulating
thread and hangs between the plates of a capacitor (see the
drawing). The ball is in equilibrium, with the thread making an
angle of 30.0o with respect to the vertical. The area of each plate
is 0.01240 m2. What is the magnitude of the charge on each
plate?

A 25. As shown in figure 9, a ball of mass M is hanging from a rope to make a pendulum. A 10 g bullet strikes the ball with a speed v = 308 m/s. The center of mass of the ball + bullet rises a vertical distance of h = 12 cm. Assuming that the bullet remains embedded, calculate the mass M of the ball. (Ans: 2.0 kg) A27. Block A (mass = 2.0 kg, velocity = 50 m/s)...
A small ball has a mass m = 4.0 x 10^-8 kg and a charge of q = -2.0 x 10^-5 C. It enters a box with an initial speed of v0 = 1.0 x 10^4 m/s. The point where the charge leaves the box has an electrical potential 350 x 10^3 higher than the entry point. (a) Find the speed of the ball as it leaves the box. (b) Suppose that the charge on the ball were q =...
7A 40kg mass is shot from a cannon at 50 m/s. The cannon recoils at 2 m/s. What is the mass of the cannon? d 105kg man is motionless on a frozen, frictionless pond. To get to the shore, he throws his 10ke a) A strande backpack at 2 m/s away from the shore. How fast does the man move? 8) b) If the pond is 30m away, how much time will it take for the man to get to...
uestion 4 (1 point) 9 m, q A ball of mass m-151.5 kg and charge q-1.22 nC (10A-9 C) is attached via a string to an infinitely large charged plane. The string makes an angle 12.55 degrees with the plane. What is the surface charge density σ of the plane in C/m^2? Use the following constants: 0 - 8.854 x 1012/N m2 g 9.81 N/m Your Answer Answer
In Figure (a), an electron is shot directly away from a uniformly
charged plastic sheet, at a speed of vs = 8.00 x 10^4 m/s. The
sheet is nonconducting, flat, and very large. Figure (b) gives the
electron's vertical velocity component v versus time t until the
return to the launch point. (The vertical axis is marked in
increments of 2.00 x 10^4 m/s.) What is the sheet's surface charge
density?

3. Magnetism a. A charge of -1.2-C is shot at 10,000m/s in the negative x-direction, passing through a magnetic field of 4T that points in the y-direction. How much force acts on the charge? And in what direction does this force point? b. A magnet with its North end facing downward is dropped through a large conducting loop. As viewed from above, which way will the induced current through the loop flow? (Explain how you get this result.) c. Two...
