  • 9702 June 2015 Paper 42 Worked Solutions | A-Level Physics



Question 1 - See solution 989 at
The Earth may be considered to be a uniform sphere of radius 6.37 × 103 km with its mass of 5.98 × 1024kg concentrated at its centre. The Earth spins on its axis with a period of 24.0 hours.



Question 2 - See solution 998 at
In a sample of gas at room temperature, five atoms have the following speeds:



Question 5
Two positively charged metal spheres A and B are situated in a vacuum, as shown in Fig. 5.1.


Question 6
An X-ray photon of energy 3.06 × 10-14 J is incident on an isolated stationary electron, as illustrated in Fig. 6.1.


Question 7 - See solution 1033 at




Question 8
The power for a space probe is to be supplied by the energy released when plutonium-236 decays by the emission of α-particles.



Question 9 - See solution 986 at
