359683 A body weight \(W\), is projected vertically upwards from earth's surface to reach a height above the earth which is equal to nine times the radius of earth. The weight of the body at that height will be

1 \(\dfrac{W}{100}\)
2 \(\dfrac{W}{91}\)
3 \(\dfrac{W}{9}\)
4 \(\dfrac{W}{3}\)
JEE - 2023

359684 The height vertically above the earth's surface at which the acceleration due to gravity becomes \(1 \%\) of its value at the surface is \((R\) is the radius of the earth)

1 \(8 R\)
2 \(9 R\)
3 \(10 R\)
4 \(20 R\)

359685 Assertion :
Generally the path of a projectile from the earth is parabolic but it is elliptical for projectiles going to a very large height.
Reason :
The path of a projectile is independent of the gravitational force of earth.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.

359686 The fractional change in the value of free-fall acceleration \(g\) for a particle when it is lifted from the surface to an elevation \(h(h < < R)\) is

1 \(h / R\)
2 \(-(2 h / R)\)
3 \(2 h / R\)
4 none of these

359687 Two equal masses \(m\) and \(m\) are hung from balance whose scale pans differ in vertical height by \(h\). calculate the error in weighing, if any, in terms of density of earth \(\rho\).
