ET. I. angular momentum: The same for both (6GM/(R))1/2 An electron traveling horizontally enters a region where a uniform electric field is directed upward. NEET 2016 Phase 1. 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. Assuming no losses to friction, how high does it get before it stops? When the two spheres are brought near each other, they swing toward each other and touch, then swing away from each other. B Two identical small metal coated spheres R and S are given identical charges of 40nC each. A quantity with subscript A or B denotes the instantaneous value of the quantity at the position A or B, respectively. Each string makes an angle theta with the vertical. The charges begin to leak from both the spheres ata constant rate. For a mass attached to a vertical spring, the vertical displacement y of the mass is given as a function of time t in the diagram. E A Two pith balls of mass 10mg are suspended by two threads from the same support and charged identically they move apart by 0.08m and the threads make an angle of 60 degrees with each other. 64 N/m Kinetic energy: Greater for S3 shorter period of oscillation (2GM/(3R))1/2 There are no forces exerted on it Two identical charged spheres suspended from a common point by two mass less strings of lengths ?, are initially at a distance d(d < < ?)

Problem: Two identical metal spheres A and B are on their insulator mountings, both initially neutral. ve/2 Kinetic energy: Less for S3 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.
