A block of mass m is in contact with the cart C as shown in the Figure
.
The coefficient of static friction between the block and the cart is . The acceleration of the cart that will prevent the block from falling satisfies:
As we learnt in
Sticking of block with accelerated cart -
For equilibrium condition
R = ma
- wherein
Pseudo force (ma) acts on block towards left
Fmin = Minimum forc
amin = minimum accleration cart
M, m are masses of cart and block respectively
