Electric field E in a region is given by where E and x is in meter A cube of side 10cm is placed in a region as shown in figure calculate 1.electric flux through the cube and 2. the net charge enclosed by the cube

 

show that the electric field for same charge density is twice in Case of a conducting sheet or surface than in a non conducting sheet

 

A charge +Q is placed on a thin conducting spherical shell of radius R use gauss's theorem to drive an expression for the electric field at a point lying (i) inside (11) and outside the shell

 

Three point Charges IPC each , are kept at the vertices of equilateral triangle of side 10cm. the find the net electric field at the centroid of the triangle

 

Two charged particles P and Q , having the same charge but different masses mp and mq start from rest and travel equal distances in a uniform electric field E in time tp and t q respectively Neglecting the effect of gravity the ratio of tp/ t q is

 

Figure shows variation of coulomb force (F) acting between two point charges with 1/ r being the separation b/w two point charges (q1 q2 ) and ( q2 q3 ) If q2 is positive and least in magnitude , then the magnitude of q1, q2 and q3 are such that
