A block of mass \( 2 \mathrm{~kg} \) is placed on the floor. The coefficient of static friction is \( 0.4 \). Force of \( 2.8 \mathrm{~N} \) is applied on the block. The force of friction between the block and the floor is
(1) \( 2.8 \mathrm{~N} \)
(2) \( 8.0 \mathrm{~N} \)
(3) \( 2.0 \mathrm{~N} \)
(4) zero
