A small sphere of charge q+67 pC and mass m-5.4 g is attached to a light string and placed in a uniform electric field e that makes an angle θ-31° with the horizontal. The opposite end of the string is attached to a wall and the sphere is in static equilibrium when the string is horizontal as in the figure shown below. (a) Construct a free body diagram for the sphere. (Submit a file with a maximum size of 1...
A block of mass M = 15 kg is suspended at rest by two strings attached to walls, as shown in the figure. The left string is horizontal and the right string makes an angle θ = 50° with the horizontal. What is the tension in the left string? (Assume the ring where the strings come together is massless.) Tleft =
A thin stick of mass 0.5 kg and length
L = 0.8 m
is attached to the rim of a metal disk of mass
M = 5.0 kg
and radius
R = 0.4 m.
The stick is free to rotate around a horizontal axis through its
other end (see the following figure).
(a)
If the combination is released with the stick horizontal, what
is the speed (in m/s) of the center of the disk when the stick is
vertical?
m/s...
An 80-kg clown sits on a 20-kg bike on a tightrope attached between two trees. The center of mass of the clown is 1.6 mabove the rope, and the center of mass of the bike is 0.70 mabove the rope. A load of what mass should be fixed onto the bike and hang 1.50 m below the rope so that the center of mass of the clown-bike-load system is 0.50 m below the rope? What is the force that the...
Problem with data for try #1 Two small beads having positive charges 3q and q are fixed at the opposite ends of a horizontal insulating rod, extending from the origin to the point x-d. As shown in the figure, a third small charged bead is free to slide on the rod. At what position is the third bead in equilibrium? Take q-1.24 HC +3q and d 70.6 cm Defined symbols d length of the rod in m q charge The...
An object with a mass of m - 4.80 kg is attached to the free end of a light string wrapped around a reel of radius R - 0.275 m and mass of M 3.00 kg. The reel is a solid disk, free to rotate in a vertical plane about the horizontal axis passing through its center as shown in the figure below. The suspended object is released from rest 6.80 m above the floor. (a) Determine the tension in...
6. Consider a two dimensional mass distribution in the shape of a thin pizza slice: The mass is uniformly distributed and the pizza slice has a radius R and total angle o. Basically you can think of this as a slice of a disk of radius R and angle φ。. a) What is the mass per unit area σ in terms of M, R, and φ? b) Calculate the center of mass of the pizza slice. Check that your answer...
A uniform beam of length 10.0 m and mass 50.0 kg is attached to a wall at one end and free to pivot at this point. The beam is held horizontal by a cable attached to the far end of the beam and to a point on the wall 5.77 m above the pivot point. The angle between the beam and the cable is 30 degrees. A. What is the tension in the cable? B. What force is exerted by...
