Answer these five questions about the situation at \(t_{1}\) in Figure 16.7, assuming the right end of the string of beads is attached to a wall that is not shown.

(a) If \(F_{43}^{c}=5 \mathrm{~N}\), what is the magnitude of the force exerted by the wall on the rightmost bead? ( \(b\) ) What is the magnitude of the horizontal component of \(\vec{F}_{12}^{c}\) ?

(c) What is the direction of the force exerted by the hand on the string?

(d) How does the magnitude of this force compare with the magnitude \(F_{43}^{c}\) ?

(e) What are the effects of the horizontal and vertical components of this force?
