Question

The graph below represents the relationship between energy and equivalent mass from which it can be converted. The slope of this graph represents
Options
A c
B c^2
Correct Answer
C 1/c
D 1/c^2
Correct Answer

Option B is the correct answer.

Detailed Explanation

According to Einstein's mass-energy equivalence principle, Energy (E) is related to equivalent mass (m) by the equation E = mc^2, where c is the speed of light in a vacuum.If Energy (E) is plotted on the y-axis and mass (m) is plotted on the x-axis, the equation takes the form y = (c^2)x.Therefore, the slope of this graph (ΔE/Δm) represents c^2.

Hint

Remember Einstein's famous equation for mass-energy equivalence.
