A chain of length L is placed on a horizontal surface as shown in Fig. 7.282. At any instant x is the length of chain on rough surface and the remaining portion lies on smooth surface. Initially x = 0. In Fig. 7.278 the blocks are at rest and a force of 10 N acts on the block of 4 kg mass. The coefficient of static friction and the coefficient of kinetic friction are mu s = 0.2 and mu k = 0.15 October 1, 2020 Category: Uncategorised (JEE Advanced Physics by BM Sharma + GMP Solutions) , Facebook Messenger WhatsApp Share this:TwitterFacebook Related
