6. A block of weight 9.8N is placed on a table. The smooth table surface exerts an upward force of 10N on the block.Assume g 9.8m/s(A) The block exerts a force of 10N on the table(C) The block exerts a force of 9.8N on the table(B) The block exerts a force of 19.8N on the tablee block has an upward acceleration.

Answer»

Take the case if the the block is accelerating upward !

Then only you can have the the table surface exerts more force then the weight!If the block exerts a force of 9.8N on the table it means the ground is not accelerating.

option d

ohk but I didn't got the last line!!!!could u make it a bit simple

a body when kept anywhere experiences normal reaction from groundit is a case of Newton's third law of motion..this action has an equal and opposite reaction.
