Question

if the angle between 2 vectors is 90 degrees and their magnitudes are 6N and 8N find the resultant force

Answer 1

Answer:

R= 10N

Explanation:

R2 = a2 + b2 + 2*a*b*cosα

Where R is resultant and α represents the angle between vectors a and b.

R2 = 6^2 + 8^2 + 2*6*8*cos90

R2 = 36 + 64 + 0

R2 = 100

Take the square root of both sides

R = 10N
