A block of weight \( 9.8 \mathrm{~N} \) is placed on a table. The
\( \mathrm{P} \) table surface exerts an upward force of \( 10 \mathrm{~N} \) on the block. Taking \( g=9.8 \mathrm{~m} / \mathrm{s}^{2} \), which of the following statement are correct ?
(a) The block exerts a force of \( 10 \mathrm{~N} \) on the table
(b) The block exerts a force of \( 19.8 \mathrm{~N} \) on the table
(c) The block exerts a force of \( 9.8 \mathrm{~N} \) on the table
(d) The block has an upward acceleration
(1) only a
(2) a and d
(3) \( b \) and \( d \)
(4) c and d
