S_1 and S_2 are two hollow concentric spheres enclosing charge Q and 2Q, respectively, as shown in figure. What is the ratio of the electric flux leaving through the surface of S_1 and S_2 ?

S_1 and S_2 are two hollow concentric spheres enclosing charges Q and 2Q , respectively, as shown in figure. i. What is the ratio of the electric flux through S_1 and S_2 ? ii. How will the electric flux through sphere S_1 change if a medium of dielectric constant 5 is introduced in the space inside S_1 in place of air. .

if S_1 , S_2 , S_3..........,S_q are the sums of n terms of q ,AP's whose first terms are 1,2,3,...........q and common difference are 1,3,5,...........,(2q-1) respectively ,show that S_1 + S_2 + S_3..........+S_q=1/2nq(nq+1)

S_1 and S_2 are two parallel concentric spheres enclosing charges Q and 2Q respectively as shown in the figure below. What is the ratio of electric flux through S_1 and S_2 ?

S_(1) and S_(2) are two concentric sphere enclosing charges 2Q and 3Q respectively as shown in the figure. What is the ratio of the electric flux through S_(1) and S_(2) ?

A conducting shell S_1 having a charge Q is surrounded by an uncharged concentric conducting spherical shell S_2 . Let the potential difference between S_1 and that S_2 be V. If the shell S_2 is now given a charge -3Q , the new potential difference between the same two shells is

S_(1) and S_(2) are two bellow concentric spheres enclosing Q and 3Q respectively as shown in Figure. What is the ration of electric flux through S_(1) and S_(2) ? What would be electric flux through S_(1) ? If air inside S_(1) is replaced by a medium of dielectric constant 3 ?

Statement I: Two point coherent sources of light S_(1) and S_(2) are placed on a line as shown in figure. P and Q are two points on that line. If at point P maximum intensity is observed, then maximum intensity should also be observed at Q. Statement II: In figure the distance |S_(1) P - S_(2) P| is equal to distance |S_(1) Q - S_(2) Q| .
