My first thought upon reading your suggestion starts with taking, 2021 Physics Forums, All Rights Reserved, Which I know is wrong because, in that case, the, Angle between 2 charged spheres hanging from string. y = 5 sin (3t) D The charge begins to leak from both the spheres at a constant rate. A If the particle starts from rest so that its speed v and position x are zero when t = 0, where is it located when t = 2 seconds? To stretch a certain nonlinear spring by an amount x requires a force F given by F = 40x -6x2, where F is in newtons and x is in meters. Two identical charged spheres suspended from a common point by two massless strings of lengths l, are initially at a distance d(d << l) apart because of their mutual repulsion. A comet moves in the Sun's gravitational field, following the path shown above. Two 0.20 g metal spheres are hung from a common point by non-conducting threads that are 30 cm long. 3 s, The Planet X has a mass M, radius R, and no atmosphere. The distances RA and RB, are the maximum and minimum distances, respectively, of the satellite from the Earth's center. The escape speed for a rocket at Earth's surface is ve. When suspended in a liquid of density = 0.8 g/cc, the angle. B A None, Two identical conducting spheres are charged to +2Q and Q. The strings make an angle of 30 o with each other. III. A A 1/2 (M+m)vo2, What is the direction of the electrostatic force on +q due to +Q and -Q, Which of the following Gaussian surfaces would be the simplest to use to determine the electric field intensity near a long straight charged wire? Which one of the following statements is true concerning the magnitude of the electric field at a point in space? A In liquid, 100 kg. 2(2)1/2 cm Two charged particles A and B are located near one another. When the two spheres are brought near each other, they swing toward each other and touch, then swing away from each other. The platform is on ice with no friction that acts on it. There will be two equation formed accordingly for the two medium. They are shot into a region that contains a uniform electric field as shown. What is the ratio of the acceleration due to gravity at the surface of the new planet to the acceleration due to gravity at the surface of Earth? positive in I, negative in III the person's weight is greater than at the surface, the person's weight is less than at the surface, The acceleration due to gravity on the surface of the Moon is about 1/6 of that on the surface of Earth. Two identical charged spheres suspended from a common point by two massless strings of lengths H, are initially at a distance d(d< < H) apart because of their mutual repulsion. by changing angular momentum Complete the following statement: When a glass rod is rubbed with silk cloth, the rod becomes positively charged as. The figure above shows a spherical distribution of charge of radius R and constant charge density. There is no friction exerted on it 1 and 2 only A particle with charge $-3.00 \mu \mathrm{C}$ and mass $2.00 \times 10^{-16} \mathrm{~kg}$ is fired from the positive plate toward the negative plate with an initial speed of $2.00 \times 10^{6} \mathrm{~m} / \mathrm{s}$. Pendulum 2 is identical to pendulum 1, but it is displaced by a very small angle 2, is released from rest, and oscillates with a period T2, where angle 1 is greater than angle 2.
