Two blocks A and B, each of mass m, are connected by a spring of force constant K. Initially, the spring is in its natural length. A horizontal constant force F starts acting on block A at time `t=0` and at time t , the extension in the spring is seen to be `l`. What is the displacement of the block A in time `t` ?

A

`R/4(e^(2omegat)+e^(-2omegat))`

B

`R/4(e^(omegat)+e^(-omegat))`

C

`R/2cos2omegat`

D

`R/2cosomegat`
