Your Physics book has a mass of 400g It is kept on a horizontal table. Taking g = 10m/s square, find the force ( both magnitude and direction ) exerted by the table on the physics book |
|
Answer» solution: MASS of physics book(m) = 400g= 0.4kg g= 10m/s² according to Newton's third law of MOTION every action has equal and opposite reaction. force DUE book on table. F= mg= 0.4×10=4N in downward direction so the force on book by table is equal in magnitude but opposite in direction. F=-F table EXERT 4N force in upward direction. |
