A solid sphere of mass \( 10 \mathrm{~kg} \) is placed on a rough surface having coefficient of friction \( \mu=0.1 \). A
\( \mathrm{P} \) constant force \( F=7 \mathrm{~N} \) is applied along a line passing through the centre of the sphere as shown in
W the figure. The value of frictional force on the sphere is
(1) \( 1 \mathrm{~N} \)
(2) \( 2 \mathrm{~N} \)
(3) \( 3 \mathrm{~N} \)
(4) \( 7 \mathrm{~N} \)
