ing down at the table force of by the channel A force in the pointing from too. of motion. A force Pointing tomo of the force is (are) acting on the ball when it is within the frictionless Position (cy and 3. (B) ap 2, and 3. a 1, 3 and 4. (A) (C) (D) in the figure would after across the frictionless table top? 7. A steel ball is attached to a string and is Nung in path as illustrated in the accompanying At the point indicated in the figure, the string suddenly breaks near the If these are above events observed from directly string as figure, which path ball breaks? follow after the (E)Explanation / Answer
Answering questions on 1st page... i. e. 5 6 and 7
5) answer is option 2 ie gravitational force and a force acting in direction from q to O.. THERE ARE NO OTHER FORCES.. only gravity and normal reaction from pipleline.
6)ans is it takes the path B.. As soon as the required centripital force ( normal reaction from pipeline) ends.. There is no force to keep the particle in curve motion... So it will follow a straight path..
7) ans is direction B for the same reason in question 6 and the velocity is in tangential direction, so it will continue to move in that direction..
8) ans is B, ie the vector sum of 2 velocities.. One of puck itself and other from the kick..
9) E its actually squre root of the sum of squares of both the velocities.
10) A is ans, as there is no external force in that plane changing the velocity... Gravity is not affecting the velocity as is perticular to the horizontal plane
11) A as explained in 10th part
Thank you.. Comment if you have any problem
