ing An elastic belt (Elasticity E, Cross-sectional area A) isning of coll lowering a mass M as the disc rotates with constant angular velocity. The constant linear velocity of the mass is V and the belt rolls without slipping on the disc. Disc mass is same as mass of the block. When the belt has lowered by L length, disc is jammed, and system suddenly comes to rest. If remaining coiled length of belt on disc is negligible, elongation of the belt due to sudden jamming is ML (a) V (b) V 3ML EA (c) V ML 2EA (d) v 2ML M 2EA EA
