The massofaball is 1.76kg . The mass of 25 such balls is

The mass of a ball is four times the mass of another ball. When these balls are separated by a distance of 10 cm , the gravitational force between them is 6.67xx10^(-7) N . The masses of the two balls are in kg .

The mass of a ball A is double the mass of another ball B. The ball a moves at half the speed of the ball. B. Calculate the ratio of the kinetic energy of A to the kinetic energy of B,

The mass of a ball if four times the mass of another ball. When these balls are separated by a distance of 10 cm, the gravitational force between them is 6.67xx10^(-7)N . Find the masses of the two balls.

What will be the wavelength of a ball of mass 0.1 kg moving with a velocity of 10 ms ^(-1).

In the arrangements shown in the figure masses of each ball is 1 kg and mass of trolley is 4 kg . In the figure, shell of mass 1 kg moving horizontally with velocity v = 6 ms^(-1) collides with the ball and get stuck to it then its maximum deflection of the thread (length 1.5 m ) with vertical
