Making free body diagram of block we can se there are 4 forces acting on block
  1. mgcos30
  2. mgsin30
  3. Friction
  4. Normal
Force trying to move the block =mgsin30=2gsin30=9.8
Maximum friction =uN=umgcos30=1.2gcos30=10.18
Maximum friction is greater than mgsin30
Thus friction acting is mgsin30=9.8
