Sketch the field lines due to a point charge (a) `q gt 0 (b) q lt 0`

Sketch the magnetic field lines for current carrying circular loop

If the direction cosines of a line are (1/c,1/c,1/c) then a) 0 lt c lt 1 b) c gt 2 c) c= pm sqrt2 d) c= pm sqrt3

Draw the electric lines of force surrounding the charges if. Br a .+ q charge and a .- q. charge are separated at a distance .a. apart in air.
