A block of weight `9.8N` is placed on a table. The table surface exerts an upward force of `10N` on the block. Assume `g=9.8m//s^(2)`.

A

The block exerts a force of 10N on the table

B

The block exerts a force of 19.8N on the table

C

The block exerts a force of 9.8N on the table

D

The block has an upward acceleration.

Text Solution

Verified by Experts

The correct Answer is:
B, D
Since `vec(a)_(1)nevec(a)_(2)` there is slipping between the two
`f = mu N`
