7. a Exp.:
Action is directed opposite to the
reaction
8. b Exp.: The tension between P and Q
acceleration double the mass as compared to that between Q and R
9. d Exp.: Here mg sin 𝑎 = 8. To make it
move up with the same acceleration, we need to apply force F such that F – mg
sin 𝑎. Because acceleration down the inclined plane is g sin 𝑎.
10. c Exp.: Let the acceleration if system be 𝑎.
Then 𝑎 = 5 N/( 6 + 4) kg
= 0.5 ms –2
