A wind turbine turns wind energy into electricity using the aerodynamic force
As we know that gravitational force on two planets will be given as
let
mass of star = M
mass of two planets are m1 and m2
their distance from star is r1 and r2
since the gravitational force of star is given on two planets to be same
so here we can say
now if the ratio of mass and distance is same then we can say that closer planet must have lesser mass to hold good for above equation
so correct answer will be
B) Yes, it is possible if the closer planet has less mass.
Answer:
Option (b) is correct.
Explanation:
The motion under the influence of gravity is called projectile motion.
The acceleration due to gravity is constant through out the motion and it is always acting downwards.
When an athlete jumps and follow the projectile path, it always have the same horizontal velocity as there is no acceleration in the horizontal direction.
Also he has the vertical acceleration constant which is equal to the acceleration due to gravity and acts towards the center of earth.
Option (b) is correct.
