Question

A body of mass 600 g slides on a rough horizontal surface. If the frictional force is 2.0 N. Then the
magnitude of reaction is (Take g = 10 ms?)
[ ]
a) 5 N
b) 7 N
c) 5710 N
d) 2710 N​

Answer 1

Explanation:

mass of body= 600g therefore.....0.6kg

frictional force= 2.0N

g=10m/s

therefore

by using this........ N=mg

0.6 × 10

6N

R=√N^2+√F^2

√6^2 +√2^2

=√36+4

=√40

=2√10

so I think it will be

2710 N

if correct give a thanks
