Question
The notation means to find the limit as x approaches a from the left only, and means to find the limit as x approaches a from the right only. These are call one-sided limits. In Einstein's theory of relativity, the length L of an object moving at a velocity v is , where c is the speed of light and L0 is the length of the object at rest. Find and explain why a limit from the left is used. Why is a limit from the left used? The function has a "jump" between values of v less than c and values of v greater than c. The function is undefined for all values of v greater than c. The function goes to infinity when approached from the right. The function is undefined for all values of v less than c.Explanation / Answer
B option is correct , the value will bw undefined
for c+ , v^2 / c^2 will be greater than one , which will make the whole thing -ve under sq root , which is not desired
