Question

The value of $R_{0}R$ is –

• A. 0
• B. 1
• C. ∞
• D. None of these

Answer 1

Answer: (A)

0

Answer 2

As we are RHL so $\lim _ { x \rightarrow 0 }$

= $\lim _ { x \rightarrow 0 }$ $\frac { x . e ^ { 1 / x } \left( \frac { - 1 } { x ^ { 2 } } \right) + e ^ { 1 / x } } { e ^ { 1 / x } \left( \frac { - 1 } { x ^ { 2 } } \right) }$ = 0
