Question

The vector sum of the forces $10N$ and $6N$ can be

• A. $2N$
• B. $8N$
• C. $18N$
• D. $20N$

Answer 1

Answer: (B)

$8N$

Given forces are 10 N and 6 N

So,

Maximum resultant magnitude of the vectors $=10+6=16N$
Minimum resultant magnitude of the vectors $=10-6=4N$
The vector sum can be anything from 4 to 16 depending on the angle between them.

From the given options only 8 N is possible.

Hence the correct option is (C)
