  1. x=0 means y-axis `rArrvec(F)_(1)=hat(j)`
    y=0 means x-axis `rArr vec(F)_(2)=2hat(i)`
    So resultant, `vec(F)=vec(F)_(1)+vec(F)_(2)=2hat(i)+hat(j)`

  1. Correct Answer – D
    `x=0` means y-axis implies `vec(F)_(1)= hat(j)`
    y=0 means x-axis `implies vec(F)_(2)= 2hat(i)`
    So resultant `vec(F)= vec(F)_(1)+vec(F)_(2)= 2hat(i)+hat(j)`
