Question

34. A body of weight 20 N is on a horizontal surface,
minimum force applied to pull it when applied
force makes an angle 60° with horizontal (angle of
friction a = 30°) is
(a) 20 N
(b) 20,3
(d) 20 N
w 20​

Answer 1

Explanation:

Let's solve...but plse award brainliest

first calculate friction co.efficient

mew = tan30= 0.6

so f= mew.N

f= 0.6×20= 12N

so force required to move is 12Nor more
