Question

Which of the following cannot be the resultant of the vectors of magnitude 5 and 10?

Answer 1

@experimentX @mukushla @Yahoo! help help!

Answer 2

7
5
8
2

Answer 3

we must use an inequality for \(|\vec a+\vec b|\)

Answer 4

Didn't get it :/

Answer 5

also we can prove \[|\vec a|-|\vec b| \le|\vec a+\vec b| \le |\vec a|+|\vec b|\]

Answer 6

so what should be your answer?

Answer 7

i think it is 2

Answer 8

Do u have the answer key

Answer 9

no..

Answer 10

\[|\vec a|-|\vec b| \le|\vec a+\vec b| \le |\vec a|+|\vec b|\]\[10-5 \le|\vec a+\vec b| \le 10+5\]\[5 \le|\vec a+\vec b| \le 15\]so it can not be 2

Answer 11

just look this the resultant should not be less than the given two vectors

Answer 12

but better to go with Expers way to understand the inequality

Answer 13

where did we get that inequality from?
