Question

hey guys:-

let's try to solve this together:-❗

DETAILED ANSWERS NEEDED☺​

Answer 1

Here

Formula used

R^2 = A^2 + B^2 + 2AB Cos theta

A= 3 N

B= 2 N

R^2 = 13 + 12 Cos theta

Case 2

4R^2 = 40 + 24 Cos theta

put the value of R^2

here we got

4 ( 13 + 12 Cos theta ) = 40 + 24 Cos theta

52 + 48 Cos theta = 40 + 24 Cos theta

Now 24 Cos theta = 40-52

Cos theta = -12 / 24

Cos theta = -1/2

Cos 120 degree = -1 /2

Theta = 120 degree
