विशिष्ट निष्कर्ष निकालेंगे। तैयार किए गए सभी निष्कर्षों को सूचीबद्ध करें। (पाठ 5 देखें)Consider an object of mass 50 kg. Estimate the weight of the object at a distance R. 2R.4R, 6R and 10R from the centre of the earth. Plot a graph showing the weight of theobject with respect to thedistance from the centre of the earth. What would happen to thegraph if the earth shrinks to half of its radius. Show on the graph how the mass of theobject varies with distance. What specific conclusions will you be able to draw from theobservations of the graph. List all your conclusions drawn.( See Lesson 5) |

Answer» Answer: We know that- g= R
GMx
for X And g= x 2
GM
for x≥R At surface, g= R 2
GM
=9.8m/s 2
At half the radius of earth, x= 2 R
g ′ = R 3
GMx
= R 3
GM 2 R
= 2 1
R 2
GM
⟹g ′ =4.9m/s 2
and hence weight will also get halved. ∴weight=125N Explanation: PLEASE mark me brain list |
