Two forces 5N and 10N act on a body in the direction due North and east respectively at an angle 75 degree. Calculate the resultant force of the inclined angle.

Hmmm. Due north and east respecdtively at an angle of 75deg? N and E are at 90 deg
5N+10N= 15N
F=ma
15N=m10kg
15/10kg=m10kg/10kg
1.5kg=0
1.5kg=m
F=ma
15N=m10kg
15/10kg=m10kg/10kg
1.5kg=0
1.5kg=m
Using parallelogram law:
R2=p2+r2-2pq cos 180-ø
=25+100-2*5*10 cos 180-75=105
=125-100(-0.2588)
=125+25.88
R2=150.88
R=√150.88=12.3
R2=p2+r2-2pq cos 180-ø
=25+100-2*5*10 cos 180-75=105
=125-100(-0.2588)
=125+25.88
R2=150.88
R=√150.88=12.3
