Question

Write a java program to calculate the time period of a Simple Pendulum by taking length and acceleration due to gravity as input​

Answer 1

import java.util.*;

class Simple

{

public static void main()

{

Scanner sc=new Scanner(System.in);

double Time,pie=22/7,length,g=9.8;

System.our.println("Enter the length of pendulum");

length=sc.nextDouble();

Time=2*pie*(Math.sqrt(length,2)/Math.sqrt(g,2));

System.out.println("Time taken by simple pendulum is "+Time);

}

}

Hope it will help@

Answer 2

Answer: correct answer..

Explanation:

import java. util.*;

class Time

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.println("Enter length and gravity ");

double l=sc.nextDouble();

int g=sc.nextDouble();

double t=2*(22.0/7.0)*(Math.sqrt(l/g));

System.out.println("time period="+t);

}

}
