A ball is attached to a thread of length L = 16.8 cm and suspended from the ceiling
(a)
A ball is attached to a thread of length L = 16.8 cm and suspended from the ceiling, as shown in the figure. A uniform electric field points to the right in the figure. When
θ = 15.5°,
the ball is in equilibrium. Find the net charge on the ball (in
µC).
A ball is attached to a thread of length Land suspended from the ceiling. The thread makes an angle θ with the normal line from the ceiling, such that the thread and ball are displaced to the right of the normal line. The ball is labeled with m = 2.00 g. To the right of the thread and ball, five parallel, evenly-spaced, identical arrows point to the right. The arrows are vertically stacked and labeled with E = 1.00 ✕ 103 N/C. To the left of the thread and ball, xy coordinate axes demonstrate that the x-axis points to the right and the y-axis points up.
(b)
What If? If the electric field is suddenly turned off, what is the speed of the ball at the bottom of its swing (in m/s)?

A uniform thin rod of mass m and length 5b is suspended from the ceiling by a single string of length 2b attached to one end (this end of the rod is called P1). Thus in equilibrium the string and rod hang straight down and the lower end of the rod is a distance 7b from the ceiling (this end of the rod is called P2). The motion is constrained to be in a fixed vertical plane, so we have...

A small 12.6 g plastic ball is tied to a very light 28.4 cm string that is attached to the vertical wall of a room.
A small 12.6 g plastic ball is tied to a very light 28.4 cm string that is attached to the vertical wall of a room. (See the figure (Figure 1).) A uniform horizontal electric field exists in this room. When the ball has been given an excess charge of -1.10μC , you observe that it remains suspended, with the string making an angle of 17.4° with the wall. Part A Find the magnitude of the electric field in the room. Part B Find the...
