g- Acceleration due to gravity. G- Universal gravitational constant. g - Varies from place to place , planet to planet G- Is constant throughout the universe.
If feather and coin are dropped from same height on earth, the coin falls faster. This is due to air resistance on feather which is negligible on coin. If they are allowed to fall in vacuum they fall together. The acceleration due to gravity is same for all object irrespective of their mass. This isRead more
In water there will be less number of waves than in glass if they have same frequency light travelling in them. If the number of waves are same in them then water should have greater length. As there is only one option greater than 16 cm which is 18 cm, 18 cm or a. is correct answer.
The gravitational force between two objects is directly proportional to product of their masses and inversely proportional to square of the distance between them. The constant which equates the force with product of mass divided by square of distance is called universal gravitational constant. G isRead more
The acceleration due to gravity on any planet increases with mass of the planet and decreases with radius of the planet. The mass of jupiter is 319 times than that of earth means the acceleration due to gravity on jupiter should be 319 times greater than that on earth only if they had same radius. BRead more

We know F = G* M1*M2/d square or d =sq root (G* M1*M2/F) = 0.063 m.

If we decrease the distance to half the force increases by 4 times, which is the square of 2. 4*100 N = 400N.
