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.

Two 1.8-g spheres are suspended by 21.0-cm-long light strings (see the figure). A uniform electric field is applied in the x-direction. If the spheres have charges of −6.0 ✕ 10−8 C and +6.0 ✕ 10−8 C, determine the electric field intensity that enables the spheres to be in equilibrium at θ = 20°. Charged spheres hang from the ends of each of two strings of identical length. The tops of each string are connected to a single attachment point on...
A small 1.45 g plastic ball that has a charge q of 1.75 C is suspended by a string that has a length L of 1.00 m in a uniform electric field, as shown in the figure. If the ball is in equilibrium when the string makes a 9.80 angle with the vertical as indicated by θ, what is the electric field strength E?

An object of mass m = 0.300 kg is suspended from the ceiling of an accelerating truck as in the figure below. Take a = 2.80 m/s2. A truck is accelerating to the right, as indicated by an arrow labeled vector a. A small sphere of mass m is suspended from the ceiling of the truck by a string. The string makes an angle θ with the vertical, and the mass hangs to the left of the vertical. (a) Find...

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...
