A particle of mass 0.5 kg is subjected to a force which varies with distance as shown in figure   1. The work done by the force during the displacement from `x=0` to `x=4and x=4` to `x=12`are respectively  `{:((1)20J","40J,(2)40J"," 40J,(3)20J","60J,(4)40J","80J):}`   2. The increaase in kinetic energy of the particle during its displac ement from `x=0` to `x=12` m is  `{:((1)20J,(2)40J,(3)80J,(4)120J):}`  3. If the speed of the particle at `x=0` is 4 m/s, its speed st `x=8` m is  `{:((1)8m//s,(2)16m//s,(3)32m//s,(4)4m//s):}`
