What is the work done in moving a $2 \mu \mathrm{C}$ point change from corner $A$ to corner $B$ of a square $A B C D$ when a $10 \mu C$ charge exists at the centre of the square?

Ans: Point $A \& B$ are at the same distance from the point $O$.
Hence,

At a certain location in Africa, a compass points $12^{\circ}$ west of the geographic north. The north tip of the magnetic needle of a dip circle placed in the plane of magnetic meridian points above the horizontal. The horizontal component of the earth’s field is measured to be $0.16 \mathrm{G} .$ Specify the direction and magnitude of the earth’s field at the location.At a certain location in Africa, a compass points $12^{\circ}$ west of the geographic north.
