Questions
A particle of mass 50 gram executing simple harmonic motion with amplitude of 5m. The maximum value of force acting on the particle during the course of oscillation with an angular frequency of 10 rad/s is
detailed solution
Correct option is A
The force responsible for simple harmonic motion is given by F=mω2x . here x is displacement From the question mass= m=50 g= 0.05 kg ,angular velocity ω=10 rad/s , amplitude= A=5 mSubstituting these in maximum values of force, put x=A to get maximum value of force F=mω2A ,on substituting the given values we get F=0.05×102×5=25N=maximum value of force acting on the particle during the course of oscillationTalk to our academic expert!
