Examiner's
Use gold nucleus.
Fig. 7.1
On Fig. 7.1, mark with an arrow the direction of the electric force on the $\alpha$-particle when it is at the point P .
[1]
(b) Fig. 7.2 shows the path of a second $\alpha$-particle approaching the gold nucleus head-on.
Fig. 7.2
At a great distance from the gold $\left({ }_{79}^{197} \mathrm{Au}\right)$ nucleus, the $\alpha$-particle has kinetic energy 4.8 MeV .
The distance of closest approach of the $\alpha$-particle to the gold nucleus is $d$.
(i) Name the form of the energy into which the kinetic energy of the $\alpha$-particle has been converted when it is at the distance of closest approach.
