What main features do you observe from this tabular representation?

A point charge +20muC is at a distance 6 cm directly above the centre of a square of side 12 cm as shown is figure. The magnitude of electric flux through the square is

Two electric charges 12 mu C and -6 mu C are placed 20 cm apart in air. There will be a point P on the line joining these charges and outside the region between them, at which the electric potential is zero. The distance of P from 6 mu C chrage is

The distance between two stations 'X and 'Y is 450 km. A train L starts at 6:00 pm from X and moves towards Y at an average speed of 60 km/h. Another train M starts from Y at 5 : 20 pm and moves towards Xat an average speed of 80 km/h. How far fromxwill the two trains meet and at what time?
