A force, 10N, drags a mass 10kg on a horizontal table with an acceleration of 0.2ms. If the acceleration due to gravity is 10ms-1, the coefficient of friction between the moving mass and the table is
-
A.
0.02 -
B.
0.08 -
C.
0.20 -
D.
0.80
Correct Answer: Option A
Explanation
(mu)mg = ma
(mu) x 10 x 10 = 10 x 0.2
(mu) = 0.02
