Questions
When a particle is performing linear SHM its KE is two times its PE at a position ‘A’ and its PE is two times its KE at another position ‘B’. Find ratio of to
detailed solution
Correct option is B
At A, KE=2PE, ⇒PE=KE/2, TE=KE+PE, substitute,TE=KE+KE2, ⇒TEA=3KEA2---(1) At B, PE=2KE, TE=KE+PE, substitute,TE=KE+2KE, ⇒TEB=3KEB----(2) according to principle of conservation of energy TEA=TEB 3KEA2=3KEB ⇒KEAKEB=21Talk to our academic expert!
