Question

find the resulantvof two vectors of magnitude 5N and 12N acting at 90degrees​

Answer 1

Explanation:

Use parallelogram law of vector addition.

You can easily find the resultant force when they are perpendicular to each other..we know that

(resultant force )= √(P^2+Q^2)+2PQ cos 90

Here teeta is 90 so

R=√(5^2+12^2)+2*5*12*cos90

R=√(25+144)+0.

R= 13

I hope you that you will find any resultant forces by using this formula
