A semi circular disc of radius `R` is placed on a smooth horizontal surface. Figure shows top view of this. If temperature is increased by `Deltat` then displacement of (coefficient of linear expansion is `alpha`): A. `B` along `x`-axis is `RalphaDeltat`B. `B` along `y`-axis is zeroC. `A` along `y`-axis is`RalphaDeltat`D. `A` along `x`- axis is `-(4R)/(3pi)alphaDeltat`

Answer» Correct Answer - B::C::D
Displacement of centre of mass is zero. So take centre of mass as origin then find displacement of all points.
