Force Between Two Conducting Spheres @joshphysics "This will cause the charges on opposite spheres to be further away from each other, and the force of repulsion to be less than in the case of a uniform surface charge distribution" Why would the force of repulsion be less ? It seems intuitive but what is the reason ? Yes,the distance increases ,but we simply cannot apply the inverse square law of coulombs force ,since they are not point charges . |

What is the role of battery across a Parallel plate capacitor having equal charge? How can we say that the electric field outside the plate is same as before the battery was connected? If we could only prove this then the constant charge density on the outside surface will hold good .Isnt it ?? |

What is the role of battery across a Parallel plate capacitor having equal charge? "The important unwavering assumption is a constant electric potential throughout the interior of a plate " How does this help in concluding that the outer charge density remains the same ? "That means that the field on the outside of the plates won't change when connecting the battery" Kindly explain it a little more .I am having diffulty with option d) |

What is the role of battery across a Parallel plate capacitor having equal charge? Thank you very much for the response ...I am having a hard time understanding how can charge remain on the outer surfaces while the plates are accumulating equal positive and negative charges on the inner surfaces . |

Direction of friction on particle placed on a rotating turntable Thank u so much... "If you watched the particle it would follow a spiral centred on the centre of the turntable until it reached the edge and flew off". Please Can u elaborate it ? |

Direction of friction on particle placed on a rotating turntable Friction opposes relative slipping between surfaces...when the particle is initially placed on the rotating turntable ..the surface under it has a tangential velocity ...so in order to oppose this slipping friction must act tangentially...how then does it act radially inward ?? |
