The displacement of a particle (in meter) from its mean position is given by the equation

y=0.2\left(\cos ^2 \frac{\pi t}{2}-\sin ^2 \frac{\pi t}{2}\right)

. The motion of the above particle is

View answer and explanation

Correct option: B

simple harmonic with amplitude

0.2 \mathrm{~m}

Option B (simple harmonic with amplitude

0.2 \mathrm{~m}

) is correct because the given equation can be simplified to a standard SHM equation with an amplitude of 0.2 m.

Assertion: A particle executing simple harmonic motion comes to rest at the extreme positions.

Reason: The resultant force on the particle is zero at these positions. A particle is subjected simultaneously to two SHM’s one along the
