Speed of particle executing simple harmonic motion with amplitude α is half of the maximum speed. At that instant, displacement of the particle is1. α/22. \(\frac{{\sqrt 3 }}{2}\alpha \)3. \(\frac{{2\alpha }}{{\sqrt 3 }}\)4. \(3\sqrt 2 \alpha\)

Answer» Correct Answer - Option 2 : \(\frac{{\sqrt 3 }}{2}\alpha \)

Equations of simple harmonic motion are as followed

\(\begin{array}{l}\dot x = A\omega \cos \omega t\\x = A\sin \omega t\end{array}\)

Maximum speed will be when cosωt is maximum i.e 1

\(\Rightarrow {\left( {\dot x} \right)_{max}} = A\omega\)

When speed is half of maximum

\(\begin{array}{l}\Rightarrow \frac{{A\omega }}{2} = A\omega \cos \omega t \Rightarrow \cos \omega t = \frac{1}{2}\\\Rightarrow \omega t = \frac{\pi }{3}\end{array}\)

At \(\omega t = \frac{\pi }{3}\), displacement will be

\(x = A\sin \omega t = \alpha \sin \left( {\frac{\pi }{3}} \right) = \frac{{\sqrt 3 }}{2}\alpha \)

Which of the following relationships between the force F on a particle and the particles position x implies simple harmonic oscillation1. F = -7x2. F = 200x23. F = 10x4. F = 5x2

Answer» Correct Answer - Option 1 : F = -7x

Simple harmonic motion is a type of periodic motion or oscillation motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement.

F = -kx

∴ F = -7x is the correct option.

How does the tilt of earth’s axis influence the change of seasons?

Answer»

If the earth’s axis is not tilted, the sun’s position will have been over the equator always. If so, both the hemispheres would receive equal amount of sunlight. There wouldn’t have been change of seasons on earth. Since the tilt is maintained throughout the revolution, the position of the sun in relation to the earth varies. The sun shifts apparently between Tropic of Cancer and Tropic of Capricorn and this results in seasons.

If function `f(x)=x-(|x|)/(x),x lt 0` `=x+(|x|)/(x),x gt 0` `=1,x=0`, thenA. `underset(x to 0^(-))(lim) `f(x) dose not existB. `underset(x to 0^(+))(lim) `f(x) dose not existC. f(x) is continous at x = 0D. `underset(x to 0^(-))(lim) f(x) ne underset(x to 0^(+))(lim) f(x)`

Answer» Correct Answer - C
Given function,
`f(x) = x - (|x|)/(x), x lt 0`
`= x + (|x|)/(x), x gt 0 = 1, x = 0`
Now, at x = 0
`LHL = underset(x to 0)(lim) f(x) = underset(x to 0^(-))(lim) (x - (|x|)/(x))`
`underset(x to 0)(lim) (x - ((-x))/(x)) = underset(x to 0)(lim) (x + 1) = 1`
`RHL = underset(x to 0^(+))(lim) f(x) = underset(x to 0)(lim) + (x + (|x|)/(x))`
`= underset(x to 0)(lim) (x + 1) = 1` and f(0) = 1
`:. underset(x to 0^(-))(lim) f(x) = underset(x to 0)(lim) f(x) = f(0) = 1`
`implies f(x)` is continuous at x = 0
