All objects fall on ground with constant acceleration, called acceleration due to gravity (in the absence of air resistances). It is constant and does not depend upon the mass of an object. Hence, heavy objects do not fall faster than light objects.
Weight of an object on the moon = 1 / 6 × Weight of an object on the Earth
Also,
Weight = Mass × Acceleration
Acceleration due to gravity, g = 9.8 m/s2
Therefore,...
We can see any object, when light reflected by that object reaches our eyes. But in the dark room, no light is reflected by the object so we are unable...
(c) B is correct but A is wrong.
EXPLANATION:
(A) is not correct because the gravitational potential inside the shell is constant =-GM/a, where a is the radius of the shell. As...
All of these
EXPLANATION:
Consider a thin spherical shell and choose r = infinity where potential is zero. At infinity V = 0, E = 0. So (a) is true. At any point outside...
