43. Physics | Electric Potential | Force on an Electric Dipole in Non-uniform Electric Field

let us study the force on a dipole. when it is placed in a non-uniform electric field. we can write that. when a dipole. of moment. p vector. is placed. in a non-uniform. electric field, of strength. e vector. then its. potential energy with the field. which is also termed as interaction energy. is given …

48. Physics | Gravitation | Gravitational Self Energy of a Uniform Hollow Sphere | by Ashish Arora

let us calculate the gravitational self energy of , a hollow sphere which is a uniform sphere of mass say m and radius r , and as we have discussed, that gravitational self energy is the work done in assembling the whole body , in bringing its constituent particles from infinity to a given shape …

40. Class 12 Physics | Electric Potential | Electric Dipole Placed in a Uniform Field | Ashish Arora

40. Class 12 Physics | Electric Potential | Electric Dipole Placed in a Uniform Field | Ashish Arora

lets discuss. about what happen when electric dipole is placed in, a uniform electric field. we know that uniform, electric field is a situation where all electric lines of forces are. parallel and equi-distance from each other. and here if we place a dipole just for, understanding in sake of simplicity i am drawing, an …
