Asked by admin @ in Physics viewed by 305 People

(B)

Select the INCORRECT statement(s);(A) Work done by static friction on an objectis always zero.A frame appear to be moving withconstant velocity from another frame,it means both the frames are eitherinertial or non-inertial.Acceleration of an object is observed tobe zero from an inertial frame, it meansno force is acting on the object.(D) Seperation between two particles is notchanging it means their relative velocityis zero.​
