- 2 units and 2 units
- 1 unit and 3 units
- 5 units and 1 unit
- 7 units and 2 units
- 5 units and 8 units
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
\[
|a-b| \le R \le a+b
\]
Step 1: Check range.
For 7 and 2: \[ 5 \le R \le 9 \] Thus 4 is not possible.
