Question

A metal sphere is hung by a string fixed to a wall. The forces acting on the sphere are shown in fig. Which of the following statements is/are correct? T N w Wall​

Answer 1

Answer:

Since the metal sphere is in equilibrium , so vector sum of forces acting on it must be 0 .

Thus a,b,c is correct .

$$\vec{R}+\vec{T}+\vec{W}=0,

So T^2  =R^2+W^2

So, b,c,d is also correct .

T Sinθ =R and T cosθ =W

Dividing them we get W tan θ =R.

a,b,c,d is also correct.
