Look at the graphs (Fig. 3.20) carefully and state, with reasons, which of these cannot possibly represent one-dimensional motion of a particle.

Which of the following figures cannot possibly represent electrostatic field lines?

Read each statement below carefully and state with reasons and examples, if ti is true or false: A particle in one dimensional motion. with positive value of acceleration must be speeding up.

Read each statement below carefully and state with reasons and examples, if it is true or false :- A particle In one-dimensional motion:- with constant speed must have zero acceleration,

Read each statement below carefully and state with reasons and examples, if it is true or false :- A particle In one-dimensional motion:- with zero speed at an instant may have non-zero acceleration at that instant

Read each statement below carefully and state with reasons and examples, if it is true or false :- A particle In one-dimensional motion:- with zero speed may have non-zero velocity,

Which among the curves shown in Fig. cannot possibly represent electrostatic field lines? :
