Given that,
Mass of ring = m
Mass of sphere = M
Radius = R
Distance = √8R
We need to calculate the intensity of gravitational field
Using formula of intensity
Put the value into the formula
We need to calculate the force of attraction between the ring and the sphere
Using formula of attraction force
Where, M = mass of sphere
E = intensity of gravitational field
Put the value into the formula
Hence, The force of attraction between the ring and the sphere is
Amplitude is the pair of vertical buttons, so to speak. Compressions are the bunched up vertical lines with the purple arrows pointing left and right. Rarefactions are purple arrows pointing down. Wavelength is crest to crest purple buttons. Associated LH and RH pointing arrows.
Explanation:
If the distance between the bottom of the ladder and the wall is x, then:
cos θ = x / 10
Taking derivative with respect to time:
-sin θ dθ/dt = 1/10 dx/dt
Substituting for θ:
-sin (acos(x / 10)) dθ/dt = 1/10 dx/dt
Given that x = 6 and dx/dt = 1.1:
-sin (acos(6/10)) dθ/dt = 1/10 (1.1)
-0.8 dθ/dt = 0.11
dθ/dt = -0.1375
The angle is decreasing at 0.1375 rad/s.
