Question

if 70 Newton and 15 Newton are opposite to 35 Newton and 20 Newton acting on a body find the net force on the body​

Answer 1

Explanation:

net force=70+15+(-35)+(-20)

=85-55=30newton

Answer 2

Answer:

8N.

Explanation:

Force acting towards north    

F  

N

​  

 

​  

=20 N    

i

^

   i.e. towards north

Force acting towards south    

F  

S

​  

 

​  

=12 N  (−

)   i.e. towards south

Resultant force    

F  

R
