A \( 2 \mathrm{~kg} \) block (A) is placed on \( 8 \mathrm{~kg} \) block (B) which rests on a table. Coefficient of friction between (A) and \( (\mathrm{B}) \) is \( 0.2 \) and between \( (\mathrm{B}) \) and table is \( 0.5 \). A \( 25 \mathrm{~N} \) horizontal force is applied on the block \( (\mathrm{B}) \), then the friction force between the blocks (A) and (B) is :-
(1) Zero
(2) \( 3.9 \mathrm{~N} \)
(3) \( 5 \mathrm{~N} \)
(4) \( 49 \mathrm{~N} \)
