Page No: 134. Answer: Let the mass, m3 = 0.5 kg be placed at a distance of ‘x’ m from m1, as shown in figure. Question 12. Time taken to reach the ground, t = 4 s Question 3. Gravitational force between moon and the earth keeps moon in uniform circular motion around the earth. Question 7: Law of gravitation gives the gravitational force between (a) the earth and a point mass only Why? Mass is the quantity of matter contained in the body. Give three differences between acceleration due to gravity (g) and universal gravitational constant (G). From the equation (1) and (2), we get Answer: F = \(G \frac{m M}{R^{2}}\) …..(1) If the small and big stones are dropped from the roof of a house simultaneously, they will reach the ground at the same time. A: mass of the object × gravitational acceleration B: Zero Calculate the average density of the earth in terms of g, G and R. Answer: It is the measure of inertia of the body. If the mass of a body is 9.8 kg on the earth, what would be its mass on the moon? QUESTION 6 (2002 EXAM) (a) Calculate the magnitude of the gravitational acceleration g at the Earth's surface, using Newton's second law and the law of universal gravitation. Question 20. (g) At which point does the bal 1 have the same speed as when it was thrown? Question 3. Thus, the packets will remain in air for longer time interval, when it is dropped at the equator. So, v2 = u2 + 2gs, i.e., weight will be reduced to one-fourth of the original. Asked by Umesh 1st December 2017 9:49 AM . Question 5. Answer: The acceleration due to gravity does not depend upon the mass of the stone or body. That is, for the second stone, t = (3.16 – 1)s = 2.16s Then weight becomes Wn = mG \(\frac{4 M}{\left(\frac{R}{2}\right)^{2}}\) = (16 m G) \(\frac{M}{R^{2}}\) = 16 × W0 It is denoted by ‘g’. Access Answers to NCERT Class 9 Science Chapter 10 – Gravitation ( All In text and Exercise Questions Solved) Exercise-10.1 Page: 134. Answer: The ratio of their accelerations due to gravity at the surface is (R 1 /R 2) 2 (R 2 /R 1) 2 ... Click the "Score and Show Answer(s)" button for explanations. Question 4. A stone dropped from the roof of a building takes 4s to reach the ground. Take the Quiz and improve your overall Physics. It occurs only when a body is in a state of free fall under the effect of gravity alone. It will remain the same on the moon, i.e., 9.8 kg. As we know s = ut + \(\frac{1}{2}\) gt2 Suppose the mass of the earth somehow increases by 10% without any change in its size. Answer: Gravitation Class 11 MCQs Questions with Answers. The moon will begin to move in a straight line in the direction in which it was moving at that instant because the circular motion of moon is due to centripetal force provided by the gravitational force of the earth. We know that g = \(\frac{G M}{R^{2}}\) or M = \(\frac{g R^{2}}{G}\) Therefore, the body appears to be floating weightlessly. ∴ v = 0 + (-10) × 2 = -20 ms-1 Weight, W = mg, m = \(\frac{W}{g}\), m = \(\frac{9.8}{9.8}\) = 1 kg (e) What is the ball’s acceleration at point A? (b) At point B Question 3. Question 7. Answer According to question, M S = Mass of the Sun = 2×10 30 kg M E = Mass of the Earth = 6×10 24 kg R = Average distance between the Earth and the Sun = 1.5×10 11 m From Universal law of gravitation, Question 19. : Weightlessness is a universal constant, i.e., Newton ( N ) objects with equal force, can say.
