Class 11th physics the charge of positive 7 microcoulomb is placed at the centre of two concentric sphere with radius 2cm and 4cm respectively what will be the ratio of flux through them

Given:

Need to find :

Calculation:

Gauss law :- ø = q/Eₒ

1. For small sphere:- ø1 = q/Eₒ

2. For large sphere :- ø2 = q/Eₒ

=> ø1/ø2 = (q/Eₒ)/(q/Eₒ)

=> ø1/ø2 = 1/1

Ratio of flux is 1:1

no

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
