Compute the angle of the strings from vertical. It is sin^-1 (8.5/40)

Call this angle A

If the string tension is T

T sin A = F (the Coulomb force)

T cos A = M g

tan A = F/Mg

You need to say what the units of the mass are. All you said was 0.09

The mass is 0.09 gm.

What does sin^-1 (8.5/40)mean. Is this sin to the negative 1 times 8.5 divided 40.

And to find T is this Mg/cosA to find T?

in this case the angle whose sine is 8.5/40

Some write this function as Arcsin ( )
