Question 1 - See solution 271 at
A stone of weight 3.0 N is fixed, using glue, to one end P of a rigid rod CP, as shown in Fig. 1.1.



Question 4
Two deuterium (21H) nuclei each have initial kinetic energy EK and are initially separated by a large distance.


Question 5 - See solution 590 at
A constant current is maintained in a long straight vertical wire. A Hall probe is positioned a distance r from the centre of the wire, as shown in Fig. 5.1.



Question 6 - See solution 992 at
A student is asked to design a circuit by which a direct voltage of peak value 9.0 V is obtained from a 240 V alternating supply.



Question 7 - Solution 1005 at
Negatively-charged particles are moving through a vacuum in a parallel beam. The particles have speed v.


Question 8
A π0 meson is a sub-atomic particle. A stationary π0 meson, which has mass 2.4 × 10-28 kg, decays to form two γ-ray photons.



Question 9
The circuit diagram of Fig. 9.1 is an amplifier circuit incorporating an operational amplifier (op-amp).
