Question

Note: It should be the same in figure2 (Yellow Page).

roblem find the weight of an object/imatter on different planets it is important first to explore the To difference between mass and weight. Mass is a measurement o is the force generated by the gravitational attraction of one o change when we change planets. f the amount it contains and weight This mass does not However, if we went from Earth to Mars, weight would change less gravity than Earth. Gravity is a force pulling matter together. Gravity of a bject on another use Mars has planet can be calculated by using following formula G M r2 Where . G is a gravitational constant whose value is 6.673x10 · M is mass of the planet in Kilograms . r is radius of the planet in meters. Diameter is equal to 2 times of radius. Weight of any object/ matter can be computed as acceleration due to gravity force (F) times mass of an object, that can be represented as w F*m Where m is the mass of an object/matter Following table shows the mass and diameter of the planets. Diameter Planets Mass (Kgs) Mercury | 3.3011 Venus 4.867x104 1 Earth 5.98x0 4.879x 10 1.2104x10 1.276x10 Mars 6417x0 6794x10 Jupiter 1.8990 1429x10 Saturn 5.6850 1205x10 1.429x10 1.205x10 5.112x10 4.953x10 Uranus 8.682x10 55 tune 1.024x1026 Pluto 1.471x10 2.37x1

Answer 1

// C++ program to calculate the mass of an object in a planet

#include <iostream>

#include <string>

#include <iomanip>

using namespace std;

int main() {

               string name;

               double mPlanet,dPlanet,rPlanet,mObject;

               cout<<"\t\tComputing Weights of objects on different Planets"<<endl;

               cout<<"********************************************************************************"<<endl<<endl;

               // inputs

               cout<<" Please enter the name of planet : ";

               cin>>name;

               cout<<" Enter the mass of Planet(M) : ";

               cin>>mPlanet;

               cout<<" Enter the diameter of Planet : ";

               cin>>dPlanet;

               cout<<" Enter the mass of an object(m) : ";

               cin>>mObject;

               const double g = 6.673e-11; // gravitational constant

               rPlanet = dPlanet/2; // calculate the radius of planet

               // calculate gravity of planet

               double fg = g*mPlanet/(rPlanet*rPlanet);

               // calculate weight of object in planet

               double w = fg*mObject;

               // output

               cout<<endl<<" "<<left<<setw(20)<<"Planet"<<left<<setw(20)<<"Gravity m/s"<<left<<"Weight of Object Kgs"<<endl;

               cout<<" "<<left<<setw(20)<<"******"<<left<<setw(20)<<"*******"<<left<<"*********************"<<endl;

               cout<<" "<<left<<setw(20)<<name<<left<<setw(20)<<fixed<<setprecision(1)<<fg<<left<<setprecision(3)<<w<<endl;

               return 0;

}

//end of program

Output:
