Question

The magnitude of the resultant of two vectors of magnitudes 5 and 3 is 2. what is the angle between the two vectors

Answer 1

Answer:

Given:

The magnitude of two vectors is 5 and 3.

Assume:

The two vectors be a and b...

Explanation:

Answer 2

HI DEAR SHRESTA HERE PLS SEE THE ANSWER...!!!!

LET THE 2 VECTORS BE A,B

R=√A^2+B^2+2ABCOS ϑ

R= √5^2+3^2+2.5.3.COS ϑ

2=√25+9+30COS ϑ

=√34+30COS ϑ

(SQUARING ON BOTH SIDES)

4=34+30COS ϑ

-30=30COS ϑ

-1=COSϑ

ϑ = 180
