Question
A block of mass m is placed on a smooth wedge of inclination . The whole system is accelerated horizontally so that the block does not slip on the wedge. The force exerted by the wedge on the block has a magnitude.
Options
A.mg
B.mg/cosθ
C.mgcosθ
D.mgtanθ
Solution
ma cosθ = mg sinθ
a = g tanθ
N = mg cosθ + ma sinθ
= mg cosθ +
=
