two forces of magnitude 30N AND 40N acts at angle of 90% to eachother.calculate the resultant of the magnitude
1 Answer
Arun
Using 2-D vector notation, this can be expressed as (30,0)+(0,40)=(30,40). So you get a net force with components of 30N along one axis and 40N along the other, giving a magnitude (via Pythagoras’ theorem) of 50N at an angle to the first axis of arctan(3/4), which is about 37 degrees

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
