A 25-kg chandelier hangs from a ceiling on a vertical 4.0-m-long wire.
Part A.
What horizontal force would be necessary to displace its position 0.12 m to one side?
Part B
What will be the tension in the wire?
Homework Answers
A)
at 12 m :
Angle from vertical, x= asin (0.12/4) = 1.72 degree
At this point:
T cos x = m*g
T*cos 1.72 = 25*9.8
T= 245.11 N
Forceapplied must baalnce T* sin x
T sin x = F
F = 245.11 * sin 1.72
F=7.36 N
B)
As calculated above,Tenstion, T= 245.11 N

A 5.61-kg ball hangs from the top of a vertical pole by a 2.43-m-long string. The ball is struck, causing it to revolve around the pole at a speed of 4.17 m/s in a horizontal circle with the string remaining taut. Calculate the angle, between 0° and 90°, that the string makes with the pole. Take g = 9.81 m/s2. What is the tension of the string?

1. A horizontal wire is hung from the ceiling of a room by two massless strings. The wire has a length of 0.11 m and a mass of 0.005 kg. A uniform magnetic field of magnitude 0.055 T is directed from the ceiling to the floor. When a current of I = 34 A exists in the wire, the wire swings upward and, at equilibrium, makes an angle φ with respect to the vertical, as the drawing shows. Find (a)...
