Question

Write a C program to calculate and display the acceleration due to gravity at the surface of the earth(g), by using the formula, where, G is gravitational constant, M is mass of the earth and R is radius of the earth

Answer 1

To calculate and display the acceleration due to gravity at the surface of the earth (g) in a C program, use the given formula and provide values for G, M, and R. Here's an example program in C that demonstrates this calculation.

Step-by-step explanation:

To calculate and display the acceleration due to gravity at the surface of the earth (g) in a C program, you can use the given formula:

g = (G * M) / (R * R)

where G is the gravitational constant (6.67 x 10^-11 N.m^2 / kg^2), M is the mass of the earth (5.9726 x 10^24 kg), and R is the radius of the earth (6,356 km or 6,356,000 meters).

Here's an example program in C:

#include <stdio.h>
#include <math.h>

int main() {
double G = 6.67 * pow(10, -11);
double M = 5.9726 * pow(10, 24);
double R = 6.356 * pow(10, 6);
double g = (G * M) / (R * R);
printf("The acceleration due to gravity at the surface of the earth is %.2f m/s^2\\", g);
return 0;
}

When you run this program, it will calculate and display the value of g, which represents the acceleration due to gravity at the surface of the earth.
