Two tiny spheres of mass 6.80 mg carry charges of equal magnitude, 72.0 nC, but opposite sign. They are tied to the same ceiling hook by light strings of length 0.530 m. When a horizontal uniform electric field E that is directed to the left is turned on, the spheres hang at rest with the angle θ between the strings equal to 58.0 ∘ ( Fig.P21.74 ).

Sep 04, 2012 · Two tiny spheres have the same mass and carry charges of the same magnitude. The mass of each sphere is 2.13 × 10-6 kg. The gravitational force that each sphere exerts on the other is balanced by the electric force. Determine the charge magnitude.
Two charged metal spheres and an ebonite rod create an electric field at a spot between the two spheres. This field has a magnitude of 2.0 N/C and is directed in the eastward direction. Determine the magnitude of the force on a charge placed at that spot mentioned before and it direction if the charge has a value of q0= +18*10-8 C.

2. In Frame 1, two identical conducting spheres, A and B, carry equal amounts of excess charge that have the same sign. The spheres are separated by a distance d; and sphere A exerts an electrostatic force on sphere B which has a magnitude F. A third sphere, C, which is handled only by an insulating rod, is introduced in Frame 2. Sphere C is
Dec 06, 2019 · Hence the net translating force on a dipole in a uniform electric field is zero. But the two equal and opposite forces act at different points of the dipole. They form a couple which exerts a torque. Torque = Either force × Perpendicular distance between the two forces x = qE × 2a sin θ X = pE sin θ [ ∵ p = q × 2a; p is dipole moment]

Dec 04, 2009 · Two small plastic spheres each have a mass of 2.0 {\rm g} and a charge of -50.0 nC. They are placed 2.0cm apart. b)By what factor is the electric force on a sphere larger than its weight? Two large, parallel, conducting plates are 17 cm apart and have charges of equal magnitude and opposite sign on their facing surfaces. An electrostatic force with a magnitude of 3.9 × 10-15 N acts on an electron placed anywhere between the two plates. (Neglect fringing.) (a) Find the electric field at the position of the electron. (b) What is

The net excess charge on two small spheres (small enough to be treated as point charges) is Q. Show that the force of repulsion between the spheres is greatest when each sphere has an excess charge Q/2. Assume that the distance between the spheres is so large compared with their radii that the spheres can be treated as point charges. 58.
