Report Report | Anurag asks : Let C be the mid-point of an arc AB of a circle such that measure of arc AB=183 degrees.If the region bounded by the arc ACB and line segment AB is denoted by S,then the centre O of the circle lies:- (a) in the interior of S (b) in the exterior of S (c) on the segment AB (d) on AB and bisects AB |
Report | Saish asks : Is it true that linear motion also has angular momentum? Can linear momentum be converted to angular? e.g. If there is a disk hinged at centre. A bullet can be fired at it such that line of motion of the bullet is parallel to plane of the disk. the bullet is fired so that it hits the disk, somewhere above the centre. After collision, the bullet sticks to disk and both undergo circular motion, having nonzero angular momentum. Since no external torque is exerted, angular momentum before and after is conserved. Hence, angular momentum before is not zero, and linear motion has angular momentum. I |
