A period of an oscillating pendulum 7 (in seconds) is given by the equation T = 2 L g where L is the length of the pendulum in meters and g = 9.8 m/s is the gravity acceleration. Write a C++ program to calculate the period of a pendulum of length L for L from 0.1 m to 0.5 m with 0.05 m interval. Display your calculation in tabular form, L vs T.
