3.50 nC of charge is consistently distributed in a solid Styrofoam ball of radius 2.00 cm cantered at x = 2.00 cm on the x-axis of a Cartesian coordinate system. -1.25 nC of charge is consistently distributed on a fibreglass spherical shell of radius 5.00 cm cantered on the source of the same coordinate system. What is the value of the electric flux by an imaginary spherical shell of radius 6.00 cm cantered on the source of the coordinate system in question?
newton; N (after Sir I. Newton, 1642-1727) The derived SI unit of force, explained as the force needed to give a mass of 1 kg an acceleration of 1 m/s 2 ; thus it has units of
Coulomb: Coulomb is the fundamental unit of charge. It is explained as the charge required to obtain 9?109 newton of force among two equal charges separated at a distance of one m
The effects of short circuits: A short circuit is a path for current where a path should not exist, the path is generally considered to have a low resistance. If a short circui

With the help of a ray diagram, explain the formation of the final image of an object in a compound microscope. Derive a mathematical expression for its magnifying power.
Q. An electron beam is accelerated through a potential difference of 104 volt. Find the de Broglie wavelength. λ = 12.27 A o / √V λ = 12.27 A o / √10 4 = 0.1227
It explains that when an object is immersed partly or completely in a liquid, it loses in weight similar to the weight of the liquid displaced by it. Let w1 be weight of an obje
