A L shaped, uniform rod has its two arms of length `l` and `2l`. It is placed on a horizontal table and a string is tied at the bend. The string is pulled horizontally so that the rod slides with constant speed. Find the angle `theta` that the longer side makes with the string. Assume that the rod exerts uniform pressure at all points on the table.
