Q-15 When a force is applied to a body, several effects are possible. Which of the following effects could NOT occur? a. The body speeds up. b. The body rotates. c. The mass of the body decreases. d. The body changes direction. e. The body remains as it was.
both c and e
no it can remain as it was. if you apply a downward force on a bed on a floor, it will remain as it was since the ground is pushing the bed upward.
but it can break up, if the applied force is much higher
the problem does not state the magnitude of the force. you can also push it lightly with your finger. that is applying a force. but it wouldn't break the bed
c only
the problem asks which of the option could NOT occur.
when u say the magnitude of force isn't mentioned, so the ans is there, it can happen
yes , couldn't occur
yes, it can happen, but it also may not happen. the problem, stated another way is: which of the following is impossible.
if something can NOT occur, it means that it is impossible
yeah, now it makes sense :)
this site is addicting :P
