Q 1. A body of mass m splits into two masses $m_1$ and $m_2$ by an explosion. After the split, the bodies move with a total kinetic energy of $T$ in opposite direction. Show that their relative speed is $\sqrt{2Tm/m_1m_2}$. [10 marks]

Q 2. Define a conservative field. Determine if the field given below is conservative in nature: $E = c[y^2 \hat i + (2xy + z^2) \hat j + 2yz \hat k]$volts per meter, where c is a constant. [10 marks]
