The diagram from below shows a pendulum. It is known that the magnitude of the tension of the wire is five times of that the weight of the sphere which is attached to. Acording to this information indicate True or False to the following statements:

I. The magnitude of the centripetal force which acts on the instant shown is $5mg$

II. The magnitude of the tangential force which acts on the instant shown is $0.6mg$

III. The magnitude of the total acceleration in the instant shown is $3\sqrt{2}g$.

The alternatives given in my book are as follows:

$\begin{array}{ll}

1.&FFF\\

2.&FTT\\

3.&FTF\\

4.&TTF\\

5.&TFT\\

\end{array}$

From my attempt I could spot is the centripetal force would be:

$F_{c}=\frac{mv^2}{R}$

The problem mentions:

$T=5mg$

From the sketch I made (and if my interpretation is correct)

Then:

$T=5mg=f_{c}$

Therefore the first statement is True.

But I'm stuck there. How can I find the other two?. Can somebody help me here?. :help:
