Light with energy flux of 24w/m^(2) is incident on a well polished disc of radius 3.5cm for one hour. The momentum transferred to the disc is

Light with an energy flux of 18 W//cm^(2) falls on a non-reflecting surface at normal incidence. If the surface has an area of 30 cm^(2) , the total momentum delivered (for complete absorption) during 30 minutes is: (a) 36xx10^(-5) kg m/s (b) 36xx10^(-4) kg m/s (c) 108xx10^(4) kg m/s (d) 1.08xx10^(7) kg m/s

A body of mass 1kg is moving with a uniform speed of 1m//s in a circular path of radius 1m . The external force acting on the body is
