## Yakeen NEET 2.0 2025 (Legend) Physics- Gravitation ### DPP: 1 **Q1** Newtons law of gravitation: - Is not applicable out side the solar system - Is used to govern the motion of satellites only - Control the rotational motion of satellites and planets - Control the rotational motion of electrons in atoms **Q2** Mass particles of 1 kg each are placed along _x_ axis at _x_ = 1, 2, 4, 8,...∞ Then gravitational force on a mass of 3 kg placed at origin is (G = universal gravitational constant) - 4G - 4G/3 - 2G - ∞ **Q3** Gravitational force between two masses at a distance _d_ apart is 6 N. If these masses are taken to moon and kept at same separation, then the force between them will become: - 1N - 6N - 36N - 6N **Q4** Three identical bodies (each mass _M_) are placed at vertices of an equilateral triangle of arm _L_, keeping the triangle as such by which angular speed the bodies should be rotated in their gravitational fields so that the triangle moves along circumference of circular orbit: - 3GM/L³ - GM/L³ - GM/3L³ - 3GM/L³ **Q5** The value of universal gravitational constant _G_ depends upon: - Nature of material of two bodies - Heat constant of two bodies - Acceleration of two bodies - None of these **Q6** Four particles of masses _m_, 2_m_, 3_m_ and 4_m_ are kept in sequence at the corners of a square of side _a_. The magnitude of gravitational force acting on a particle of mass _m_ placed at the centre of the square will be: - 24m²G/a² - 6m²G/a² - 4√2Gm²/a² - Zero **Q7** The tidal waves in the seas are primarily due to: - The gravitational effect of the sun on the earth - The gravitational effect of the moon on the earth - The rotation of the earth - The atmospheric effect of the earth it self **Q8** During the journey of space ship from earth to moon and back, the maximum fuel is consumed:- - Against the gravitation of earth in return journey - Against the gravitation of earth in onward journey - Against the gravitation of moon while reaching the moon - None of the above **Q9**
