A block of weight 9.8 N is placed on a table. The table surface exerts an upward force of 10 N on the block. Assume g = 9.8 m/s 2 .
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, d)
Newton's third law states that force applied by one object on other is exactly of same magnitude that applied by other on first. As net force on the block is in upward direction hence the block accelerates in upward direction.
