when it is known that the lengths of the two adjacent sides of the parallelogram viz. 6 and 10, is it possible to find the length of the diagonal containing that.

Any help.

Thanks

My original question is

the vector sum of the forces of magnitude 10N and 6N can be

(a) 2N (b) 8N (c) 10N and (d) 18N

I thought the vector sum would be the diagonal of parallelogram.

Then how to go about this sum.

am I on the right track?

Kindly guide me. - Jan 9th 2012, 12:56 AMprincepsRe: how to find the length of the diagonal in a parallelogram
Hint: Use Triangle Inequality Theorem to eliminate solutions that are not possible...

I have gone through the link. Thank you. According to that except the option (a) 2N rest of the options are possible. Is it okay?
