Vector A has magnitude of 5 units and makes an angle of 30∘ with the x-axis. Vector B has magnitude 10 units & make an angle of 60∘ with the x-axis. Find →A+→B
Two forces(→P+→Q) and (→P−→Q) where →P⊥→Q. when act at an angle θ1 to each other, the magnitude of their resultant is √3(P2+Q2). when they act an angle θ2, the magnitude of their resultant becomes √2(P2+Q2). This is possible only when θ1<θ2.
In the situtation given above. θ1=60o and θ2=90o In the light of the above statements choose the most appropriate answer from the options given below:
- Both statement I and Statement II are false
- Statement I is true but Statement II is false.
- Statement i is false but Statement II is true.
- Both Statement I and Statement II are true.
Two vectors having equal magnitudes of A make an angle θ with each other. Find the magnitude B of the resultant vector and the angle it makes with any one of the vectors?
B = 2 A cos ,
B = A ,
B = A cos ,
B = 2 A cos ,

Vector A has magnitude of 3 units and makes an angle of 30∘ with the positive x-axis.
Vector B has magnitude of 4 units and makes an angle of 120∘ with the positive x-axis.
Find the magnitude of the resultant and the angle that it makes with the positive x-axis.
How will you write the vector joining points P(1, 3, 2) and Q(4, 2, 1)? Also write the unit vector for →PQ
Given two vectors a vector and b vector where b makes an angle theta with the positive direction of a as shown. Find the magnitude of the resultant according to triangle law in this case.
I tried and i think have the answer in the first attempt.
I am trying but I am stuck
I tried and did not get the answer initially but after a few attempts I think I have the right answer now.
I didn't try and don't want to do it on my own. I want to watch you doing it and spoon feed me like a baby
Two vectors have magnitudes 3 unit and 4 unit respectively. What should be the angle between them if the magnitude of the resultant is 5 unit
