    Question : a) Ionized hydrogen atoms are accelerated from rest in the vacuum between two vertical parallel conducting plates . the potential differnce between the plates is V as a result of accelertation each ion gain energy of 1.9*10^-18 J find the value of V ) b) the plates in (a) are replaced by a cell that has an emf of 12 V and internal resistance 5 ohms . A resistor R is connected in series with the cell . The energy transferred by the cell to an electron as it moves through the resistor is 1.44*10^-18 J Show that the value of R is 15.0 Ohms . I Know how to find a but how can it show the answer to b ??

    Q) Radioactive element P has a half-life of 30 days and element Q has a half-life of 20 days. Initially a radioactive source contains equal numbers of each element. What is the ratio ( number of atoms of P / number of atoms of Q) after 60 days have elapsed? A. 1/2 B. 2/3 C. 3/2 D. 2 Why the answer D ? shouldn't it be B ?

    Can you clarify to which questions of which part of the paper you are referring? This question is about gravitational fields and potential part b ) A binary star system consists of two stars with masses M1 and M2 rotating about a common centre. The centres of the two stars are separated by a distance R = 1.2 × 1010 m. bii) (ii) determine the distance x at which the gravitational field strength due to the two stars is zero.
