have u drawn fbd????
if yes then answer will be in front of u...[1][1]
A cube of mass 2kg is held stationary against a rough wall by a force F=40N pass through centre C.Find perpendicular distance of normal reaction between wall and cube from point C.Side of the cube is 20cm.

hmmmmm.........i did draw FBD............but still didnt get.............
JUST SEE THAT friction=2g=20NNORMAL REACTION=40NHENCE,ABOVE WE KNOW THAT SYSTEM IS IN RESTSO AT MIDPOINT C Total friction distance from c is 10 and the normal reaction assume x then 20*10=N*x solving this we get x=5cm
