A 2 kg cookie tin accelerated at 3 m/s2 towards N-E at an angle of 50o off E direction over a friction less horizontal surface. The acceleration is caused by three horizontal forces of F1= 10 N (S-W 30o off W), F2 = 20 N towards N. What is the third force F3 in unit vector notation and in magnitude angle notation?
