Questions
At the equilibrium position of a particle executing SHM
a
restoring force acting on the particle is zero
b
the velocity of the particle is maximum
c
potential energy is minimum
d
all the above
detailed solution
Correct option is D
Force=F = -kx k is force constant x is displacement at x=0,Force = -k(0) F=0 velocity of particle,v=ωA2-x2 v2=ω2A2-x2 at x=0, Kinetic energy of particle =12mω2A2-02= maximum PE=12mω2x2 at x=0, PE=0 Potential energy=PE=minimumTalk to our academic expert!
