Two simple harmonic motions are represented by y_(1)=5[sin2pit+sqrt(3))cos2pi t] and y_(2)=5sin(2pit+(pi)/(4)). The ratio of their amplitude is : |

Answer» `1:3` `=10[(1)/(2)sin 2pi t+(sqrt(3))/(2)cos 2pi t]` `=10[cos""(pi)/(3)sin2pi t+sin""(pi)/(3)cos 2pi t]` `y_(1)=10 sin(2pi t+(pi)/(3))` `y_(2)=5sin(2pi t+(pi)/(4))` So ratio of amplitude of `y_(1)` and `y_(2)` is `(10)/(5)=(2)/(1)` So CORRECT choice is (d). |
