    Capacitors in series and Parallel

    See, for parallel condition, the voltage across each capacitor has to be same. In the second figure the capacitors are arranged in series or papallel can be decided form where the charge is flowing, the end points A and B as told by gneill matter. In his two diagrams both the capacitors have...

    Maximum Velocity for Elliptical Orbit

    I have done the following things: 0.5mv^2=GMm/4R. Then 0.5 Mβ^2V^2-GMm/4R=-GmM/R. What's the mistake here?

    Variable Magnetic field bound in a cylindrical region

    See, if you have solved the sum of electric flux( i.e flux through one face of a cube containing a charge Q inside it.=Q/6e0) you can understand.The similar follows here...Instead of Surface integral here is the line integral..

    Rotational Mechanics - Question

    As there is no acceleration of centre of mass the CM moves in a straight line its falls downwards so the end point moves L/2 Distance.

    Mechanics Problem: Sliding Ring and Hoops on a Rough Surface

    See i had a diagram..but it is in GGB FILE..For at loss.. I am telling Draw two intersecting circles..Name the topmost point as A..The ring is at A and the centres of the circles are B and C.B and C are the loops. Did it help?? or what's your confusion??

    Maximum Velocity for Elliptical Orbit

    Homework Statement A satellite is at an altitude of 3R (R- Radius of the planet) circulating around the planet with a velocity v. In order to make its path elliptical the velocity is changed from v to βv. What should be maximum value of β such that the satellite doesn't collide with the...

    Disk on a Motion: Find the Coordinates of Point A at t= 4piR/v

    Homework Statement Adisk of radius R centred at the origin is placed on a frictionless x-y plane with origin as the centre of the disk.At t=0, the disk is given initial motion such that the point A(R,0) has velocity v towards +ve x-axis and ω=v/2R. Find the coordinates of Point A at t=...
