A 5.39-kg ball hangs from the top of a vertical pole by a 2.45-m-long string. The ball is struck, causing it to revolve around the pole at a speed of 4.79 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?

A small spherical insulator of mass 8.0 × 10-2 kg and charge (left) +0.500 μC is hung by a thin wire of negligible mass. An identical spherical mass with a negative charge of -1.900 μC (right) is held 0.20 m away from the sphere and directly to the right of it, so the wire makes an angle with the vertical (see the drawing). What is the magnitude of tension in the wire? (m g/cosθ = 0.813 N) What is the...

Two wires are parallel, and one is directly above the other. Each has a length of 38.6 m and a mass per unit length of 0.0267 kg/m. However, the tension in wire A is 47.3 × 102 N, while the tension in wire B is 1.50 × 102 N. Transverse wave pulses are generated simultaneously, one at the left end of wire A and one at the right end of wire B. The pulses travel toward each other. How much...

A horizontal wire is hung from the ceiling of a room by two massless strings. The wire has a length of 0.22 m and a mass of 0.009 kg. A uniform magnetic field of magnitude 0.075 T is directed from the ceiling to the floor. When a current of I = 31 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) the...
