A pair of perpendicular vectors...
√
This thread contains 2 questions that are similar.
A pair of 482.5 N vectors are perpendicular.
What is the magnitude of their resultant?
Answer in units of N
Two vectors of magnitudes 24 N and 31.1 N
act at right angles to each other.
What is the magnitude of their resultant?
Answer in units of N
for the first one, what do u exactly do? just find the resultant and that's it? is their a magnitude sign such as north of east or something? do i have to find theta?
for the second one, what does it mean it acts of right angles ot each other? is it just the resultant or what?
1st: 482.5 ^2 + 48.5^2= r^2
232806.25 + 232806.25 = r^2
√465612.50=r^2
r= 682.358 <----does it need a positive or negative sign?2nd: 24^2 + 31.1^2 = r^2
576 + 967.21 = r^2
√1543.21= r^2
r= 39.3219 <--- did I even solve this right?
