WB JEE 2008 | Simple Harmonic Motion Question 1 | Physics

WB JEE 2008

MCQ (Single Correct Answer)

-0.25

Two springs are joined and attached to a mass of 16 kg. The system is then suspended vertically from a rigid support. The spring constant of the two springs are K₁ and K₂ respectively. The period of vertical oscillations of the system will be

$${1 \over {8\pi }}\sqrt {{K_1} + {K_2}} $$

$$8\pi \sqrt {{{{K_1} + {K_2}} \over {{K_1}{K_2}}}} $$

$${\pi \over 2}\sqrt {{K_1} - {K_2}} $$

$${\pi \over 2}\sqrt {{{{K_1}} \over {{K_2}}}} $$

A particle is subjected to two simple harmonic motions in the same direction having equal amplitudes and equal frequency. If the resultant amplitude is equal to the amplitude of the individual motion, the phase difference ($$\delta$$) between the two motion is

$$\delta = {\pi \over 3}$$

$$\delta = {{2\pi } \over 3}$$

$$\delta = \pi $$

$$\delta = {\pi \over 2}$$
