A particle executing simple harmonic motion comes to rest at the extreme positions. Is the resultant force on the particle zero

Answers (10)
No. Because x = A, at extreme. and Force is given as F=-kx So a= max\ at\ extreme\ position, i.e., at\ x=\pm A, \ a=\pm\omega^2A

sir can you explain about diode

 

no it is no zero bec acc is maximum.

F=-kx

so when x maximum at extreme then force would be maximum

but velocity is zero consiter a spring block system for better understanding

no at extreme partical have zero velocity but it has  pick level accelarationthen it should have force F=M.A

yes ,because acc becomes zero

Zero
