Draw (and upload) a free-body-diagram for block B under the conditions described in question 4 (immediately before this question). The only object in this diagram should be block B, and only forces appropriate for a free-body-diagram of block B should appear. All force vectors must be labeled with letters and subscripts as defined for this class.
