As a researcher, you are trying to obtain some 2D materials using exfoliation. You put some adhesive tape onto a piece of graphite that is 2 cm by 3 cm. You pulled the tip of the tape at an angle of 35° from the horizontal direction, and the tip of a thin graphene sheet of about 0.001 mm started to be separated from the bulk. How much force did you apply on the tape? The exfoliation strength of graphene is 21.9 × 106 N/m² Таре Таре Таре Side view (magnified) Top view
