A block of mass m is placed on a smooth slope of angle theta. The whole system (slope + block) is moved horizontally with acceleration a in such a way that the block does not slip on the slope.Hence, a =………..

Answer»

`G tan theta`
`g sin theta`
`g COS theta`
`(g)/(sin theta)`

Solution :As blockdoenstslipon slope
`m a COSTHETA= mgsin theta `

` a= g(sin theta )/(cos theta )`
` a=g tan theta`
