A block of mass \( 2 \mathrm{~kg} \) is kept on the floor. The coefficient of static friction is 0.4 . If a force \( F \) of 2.5
\( \mathrm{P} \) Newtons is applied on the block as shown in the

W figure, the frictional force between the block and the floor will be.
(1) \( 2.5 \mathrm{~N} \)
(2) \( 5 \mathrm{~N} \)
(3) \( 7.84 \mathrm{~N} \)
(4) \( 10 \mathrm{~N} \)
