The number of particles is given by n = -D n2 – n1 / x2 – x1 crossing a unit area perpendicular to X-axis in unit time, where n1 and n2 are the number of particles per unit volume for the value of x meant to x2 The number of particles is given by n = -D n2 - n1 / x2 - x1 crossing a unit area perpendicular to X-axis in unit time where n1 and n2 are the number of particles per unit volume for the value of x meant to x2 September 14, 2020 Category: Uncategorised (JEE Advanced Physics by BM Sharma + GMP Solutions) , Facebook Messenger WhatsApp Share this:TwitterFacebook Related
