Answer:
Explanation:
The vertical component of the acceleration of a sailplane is zero , that means the sailplane is experiencing net force of zero in vertical direction . Its weight is acting in downward direction . So airplane is also experiencing an upward force equal to its weight which is making net force equal to zero on it . This force is given as 5.20 k N .
So sailplane is experiencing an upward force equal to its weight . This force is generated due to air pushing up against its wings .
We know that every force generated has equal and opposite reaction force . Air is generating force on wings of sailplane , hence wings will also exert equal force on air on downward direction . This force will be transmitted to the earth by air .
Hence the gravitational force on Earth due to the sailplane will be equal to weight of sailplane . This force is 5.2 kN .
