Question
A cart of mass M has a block of mass m attached to it as shown in the figure. Co-efficient of friction between the block and cart is m. What is the minimum acceleration of the cart so that the block m does not fall?
Options
A.μg
B.μ/g
C.g/μ
D.none
Solution
Solving from the frame of cart , we get
N = ma, mg = μN
⇒ mg = μma ⇒ a =
