Two metal spheres, one of radius R and the other of radius 2R, both have same surface charge density σ. If they are brought in contact and separated, then the new surface charge densities on each of the sphere are respectively both have same surface charge density σ. If they are brought in contact and separated one of radius R and the other of radius 2R then the new surface charge densities on each of the sphere are respectively Two metal spheres August 17, 2020 Category: Chapter 20 - Electric Field and Potential , NEET Last 32 Years Solved 1988 - 2019 Physics and Chemistry Video Solutions , Physics , Facebook Messenger WhatsApp Share this:TwitterFacebook Related Two metal spheres, one of radius R and the other of radius 2R, both have same surface charge density sigma. They are brought in contact and seperated. What will be new surface charge densities on them ?Two isolated metallic solid spheres of radii R and 2R are charged such that both of these have same charge density σ. The spheres are located far away from each other and connected by a thin conducting wire. Find the new charge density on the bigger sphere.There are three concentric thin spheres of radius a, b, c ( a> b> c ). The total surface charge densities on their surfaces are σ,−σ,σ respectively. The magnitude of the electric field at r (distance from centre) such that a> r> b is:
