A block is lying at rest inside a bus. The maximum acceleration of the bus such that the block remain stationary (the static friction coefficient =02 , acceleration due to gravity =10 ~ms ⁻² )
Options
- A1 ~ms ⁻²
- B0.5 ~ms ⁻²
- C2 cms ⁻²
- D2 ~ms ⁻²
Correct answer
D. 2 ~ms ⁻²
Step-by-step solution
Due to acceleration of bus, block experiences a backward acceleration a Block will move if m a f Where, f= friction force aligned & m a m g a g=0.2 10 & a 2 ~ms ⁻² aligned Hence, maximum acceleration of the bus such that the block remain stationary is 2 ~m / s ^2 .
