Q1) Answer all Multiple Choice questions.i) Newton’s 1st law is:A. PHYSICALLY INDEPENDENT of the other two laws
of motion and CANNOT be dispensed with as an axiom
of Newtonian physics.B. PHYSICALLY INDEPENDENT of the other two laws
of motion, but nonetheless it CAN be dispensed
with as an axiom of Newtonian physics.C. Actually a SPECIAL CASE of the 2ND LAW. The
case when the net force is zero. Therefore, logically we need only
two laws of motion. Perhaps for clarity...
