CUET Level I JEE Mock Test -9 (Physics)

The universal law of gravitation is force law also known as the

• Triangular law

• Square law

• Inverse square law

• Parallelogram law

Two bodys of masses 4 kg and 9 kg are separated by a distance of 60 CM ya 1 kg mass is placed in between these two masses if the net force number 1 kg 0 then its distance from 4 kg mass is

• 26 cm

• 30 cm

• 28 cm

• 24 cm

Two identical made of the same material or capture the distance be apart then the gravitational attraction between them is proportional to

• D^-2

• D²

• D⁴

• D

The acceleration due to gravity on the surface of a planet is 14th of the value on earth when a brace ball is brought to this planet its

• Mass is halved

• Weight is halved

• Mass become one fourth

• Weight becomes one fourth

The depth the at which the value of acceleration due to gravity becomes 1/n Times the value of the earth surface is

• D= R(n/n-1)

• D= R(n-1) /2n

• D=R(n-1) /n

• D= R² (n-1) /n

The acceleration due to gravity

• Varies as 1/r above surface of the earth and 1/r² below it's surface

• Varies as 1/r² above and below surface of earth

• Varies as 1/r² below surface of earth and as r above it's surface

• Varies as r below surface of earth and 1/r² above it's surface

If mass M is split into two parts M and (m-m) which are them separated by air distance the ratio of m/m that maximizers the gravitational force between that two parts is

• 1:2

• 1:1

• 2:1

• 1:4

If the density of the Earth is doubled keeping its radius constant then acceleration due to gravity present value will be

• 2.45ms^-2

• 4.9ms^-2

• 9.8ms^-2

• 19.6ms^-2

Behind at which the acceleration due to gravity decreases by 36 percentage of its value on the surface of the Earth is assume radius of the earth is R

• R/4

• R/2

• R/6

• 4R

The distance from the centre of the Earth where the weight of the body or 014 that are the weight of body on the surface of earth are

• 0,R/4

• 0,3R/4

• R/4, 0

• 3R/4, 0
