A uniform cylinder rests on a cart as shown. The coefficient of static friction between the cylinder and the cart is `0.5` If the cylinder is `4 cm` in diameter and `10 cm` in height, which of the following is the minimum acceleration of the cart needed to cause the cylinder to tip over ?
.

Answer

4

Explanation

Maximum acceleration of cart so that cylinder does not slip: `a_(m)=mug=0.5xx10=5ms^(-2)`
For tipping over : let accelerationn of cart a.

considering torque about `A`:
`Maxxgemgxx2`
`implies age2g/5=4ms^(-2)`
