Explanation:
We shall apply length contraction einstein's relativistic formula to calculate the length observed by observer on the earth . For the observer , increased length will be observed for an observer on the earth
L= 2.05
The length will appear to be 2.05 m . and width will appear to be .5 m to the observer on the spaceship. . It is so because it is length which is moving parallel to the direction of travel. Width will remain unchanged.
If total charge Q is enclosed in the surface of cube
then we will have say that total flux linked with all surfaces of the cube will be given by
since the position of charge is symmetric with respect to the center of the cube so here this whole flux will be equally linked with each of the face of the cube
So here total 6 faces of the cube is there and the total flux of the charge will equally divide in these 6 faces
so flux linked with each face is given by formula
so each face will have above flux due to central position of charge Q
