A block of mass $m$ attached to an ideal spring undergoes simple harmonic motion. The acceleration of the block has its maximum magnitude at the point where :

চিত্রে m ভরের বস্তুটি অনুভূমিক ঘর্ষণহীন তলে সরল ছন্দিত গতিতে স্পন্দিত হচ্ছে। m = 10 kg, স্প্রিং ধ্রুবক = 30 Nm$^{-1}$

কোন অবস্থানে বস্তুটির ত্বরণ সবচেয়ে বেশি?

"The motion of a particle with a restoring force gives oscillatory motion". Which of the following force can be a restoring force for the oscillatory motion.

A mass $m$ is suspedend from the two coupled springs connected in series. The force constant for springs are $K_1$ and $K_2$. The time period of the suspended mass will be ;

The elastic potential energy of a stretched spring is given by $E=50{x}^{2}$ where $x$ is the displacement in meter and $E$ is in joule, then the force constant of the spring is
