Topic: Electrostatics An electric field line emerges from a positive point charge + q1 at an angle α to the straight line connecting it to a negative charge – q2. At what angle β will the field line enter the charge – q2? What we see in the diagram here is a cross-sectional diagram of a 3-dimensional situation. Field lines will emanate ...more»

Topic: Electrostatics Q: Small identical balls with equal charges are fixed at the vertices of a regular polygon with 2001 sides, each of length l. At a certain instant, one of the balls is released, and a sufficiently long time interval later, the ball adjacent to the first ball is released. The kinetic energies of the released balls are found to ...more»

Topic: Electrostatics/Mechanics Q. Two small balls having the same mass and charge and located on the same vertical at heights h1 and h2 are thrown in the same direction along the horizontal at the same velocity v. The first ball touches the ground at a distance l from the initial vertical. At what height H will the second ball be ...more»

Topic - Electrostatics/Mechanics Q: Two small balls of mass m, bearing a charge q each, are connected by a non-conducting thread of length 2l. At a certain instant, the middle of the thread starts moving at a constant velocity v perpendicular to the direction of the thread at the initial instant. Determine the minimum distance d between the balls. This problem ...more»
