Draw two parallel lines at a distance of `4 cm` apart

Draw two parallel lines at a distance of 2.2 cm apart.

Draw two parallel lines at a distance 5cm apart.

In a trapezium, the two non-parallel sides are equal in length, each being of 5 units. The parallel sides are at a distance of 3 units apart. If the smaller side of the parallel sides is of length 2 units, then the sum of the diagonals of the trapezium is

Two equal smooth sphere of radius a are moving with equal speed u in opposite directions along parallel lines which are a distance a apart. The coeficient of restitution between them is 1/3.Find their velocities after impact.

Two long parallel wires are at a distance 2d apart. They carry steady equal currents flowing out of the plane of the paper , as shown. The variation of the magnetic field B along the line XX is given by

Draw a line PQ. Draw another line parallel to PQ at a distance of 3cm from it.

Two charges +20 muC and -20 muC are held 1 cm apart. Calculate the electric field at a point on the equatorial line at a distance of 50 cm from the center of the dipole.
