Question

There is an old physics joke involving cows, and you will need to use its punchline to solve this problem

Answer 1

Answer:

The angle of deflection will be "1.07 × 10⁻⁷°".

Explanation:

The given values are:

Mass of a cow,

m = 1100 kg

Mass of bob,

mb = 1 kg

The total distance between a cow and bob will be,

d = 2 m

Let,

The tension be "t".

The angle with the verticles be "$\theta$".

Now,

Vertically equating forces

⇒  $T\times Cos \theta =mb\times g$ ...(equation 1)

Horizontally equating forces

⇒  $T\times Sin \theta = G\times M\times \frac{mb}{d^2}$ ...(equation 2)

From equation 1 and equation 2, we get

⇒  $tan \thata=\frac{G\times M}{g\times d^2}$

O putting the estimated values, will be

⇒  $\theta = tan(\frac{6.674\times 10^{-11}\times 1100}{9.8\times 2^2} )$

⇒  $\theta = 1.07\times 10^{-7}^{\circ}$
