1.	A bob of mass 0.1 kg hung from the ceiling of a room by a string 2m ling is set into oscillation. The speed of the bob at its mean position is 1ms^(-1). Then the trajectory of the bob if the string is cut when the bob is (a) at one its extreme positions, (b) at its mean position.
Answer» <html><body><p></p>Solution :(a) We <a href="https://interviewquestions.tuteehub.com/tag/know-534065" style="font-weight:bold;" target="_blank" title="Click to know more about KNOW">KNOW</a> that at each <a href="https://interviewquestions.tuteehub.com/tag/extreme-981946" style="font-weight:bold;" target="_blank" title="Click to know more about EXTREME">EXTREME</a> position, velocity of the bob is zero. If the string is cut at the extreme position, it is only under the action of .g.. Hence the bob will fall vertically downwards.<br/> (b) At the mean position,velocity of the bob is <a href="https://interviewquestions.tuteehub.com/tag/1-256655" style="font-weight:bold;" target="_blank" title="Click to know more about 1">1</a> m/s. along the tangent to the are, which is in the horizontal direction. If he string is <a href="https://interviewquestions.tuteehub.com/tag/cur-2040179" style="font-weight:bold;" target="_blank" title="Click to know more about CUR">CUR</a> at mean position, the bob will behave as a horizontal projectile.</body></html>
