This opamp is used to design a non-inverting amplifier with a gain of two shown in Fig. Q4b.

The plan is to demonstrate this circuit to students in a workshop. Alas, the instructor forgot to bring the probe to class. The only cable available is a 2 metre coaxial cable with capacitance of 100 pF/m.
