Two forces of 4 dyne and 3 dyne act upon a body . The resultant force on the body can be only be :

Options

A. mare than 3 dyne
B. more than 4 dyne
C. between 3 and 4 dyne
D. between 1 and 7 dyne

Answer

D

Explanation

Let `vecF_(1) = 4 "dyne"` and `|vecF_(2)| = 3` dyne
Then `" "F_(r)= |vecF_(1) + vecF_(2)|_("max") = 7 "dyne"`
`" "|vecF_(1) + vecF_(2)|_("min") = 1 "dyne"`
So, between 1 and 7 dyne .
