Questions
If Px=2 sin t and py = 2cost, then the angle between linear momentum p and force F will be
a
30°
b
45°
c
60°
d
90°
detailed solution
Correct option is D
Given that, px=2sint and py=2cost∴p=pxi+pyj=(2sint)i+(2cost)j....(1)We know that P = dp/dtSo, F=(2cost)i−(2sint)j....(2)from eqs. (1) and (2), p.F = 0So, the angle between p and F is 90°Talk to our academic expert!
