An accelerator performs an amount of work W1 to increase the speed of an electron 0.01c, from 0.13c to 0.14c. Sometime later, it does work W2 to increase the speed of the electron 0.010 again, from 0.94c to 0.95c. The relationship between W1 and W2 is:

A. W1² + W2² = constant
B. W1 = W2
C. W1 > W2
D. W1 < W2
E. None of the above
