Answer:
2023857702.507m
Explanation:
recall from newton's law of gravitation
G=gravitational constant
mshew=50g
melephant=5*10^3kg
rearth=radius of the earth 6400km or 6400000m
mearth= masss of the earth
Gm(shrew)m(earth)/r(earth)^2 = Gm(elephant)m(earth)/r^2
strike out the left hand side and right hand side variables
m(shrew)/r(earth)^2 = m(elephant)/r^2
r^2 = m(elephant).r(earth)^2 / m(shrew) .........make r^2 the subject of the equation
r^2=
r^2=40960000000000
r=2023857702.507m
Here the weight is hung from the thread inside the ceiling of train
now the FBD of train is analysed
We can say
now by ratio of two equations we have
this shows that train must be in accelerating condition due to which the thread is making an angle with the vertical
now we will have
2 The train is not an inertial frame of reference.
Since train is accelerating so it must be non inertial frame
5 The train may be moving at a constant speed in a circle.
Since its moving in circle so it is in accelerating condition
8 The train must be accelerating.
