Two objects have the same size and shape, but one is much heavier than the other. When they are dropped simultaneously from a to
1 answer:
Answer:e
Explanation:
Given
Size and Shape of two objects are same but have different mass
When they are dropped suppose from a height of h m
they reach the ground at the same time
velocity with which they reach ground is same because velocity is given by
But the momentum possessed by the heavier mass will be greater because Momentum is the Product of mass and velocity.
Velocity is same therefore mass will decide the magnitude of momentum .

The acceleration due to gravity of Mars is
<u>Explanation:</u>
As per universal law of gravity, the gravitational force is directly proportional to the product of masses and inversely proportional to the square of the distance between them. But in the present case, the gravity need to be determined between Mars and the object on Mars. Since the mass of Mars is greater than the mass of any object. Thus,
Here, G is the gravitational constant, R is the radius of Mars and M, m is the mass of Mars and the object respectively..
Also, according to Newton’s second law of motion, the acceleration of any object will be equal to the ratio of force exerted on it to the mass of the object.
So in order to determine the acceleration due to gravity of Mars, divide the gravitational force of Mars by mass of object on the surface of Mars.
