Question Detail

The relationship between energy (E) and equivalent mass (m) is given by Einstein's famous equation: E = mc2, where 'c' is the speed of light. In this graph, energy (E) is plotted on the Y-axis and equivalent mass (m) is plotted on the X-axis.The slope of a graph is given by ∂Y/∂X. In this case, the slope is ∂E/∂m.From E = mc2, we can see that if we differentiate E with respect to m, we get ∂E/∂m = c2.Therefore, the slope of the graph represents the square of the speed of light.
