False. First Law of Newton states that object tends to be at rest until an external force is applied and vice-versa.
Answer:
Work done by external force is given as
Explanation:
As per work energy Theorem we can say that work done by all force on the car is equal to change in kinetic energy of the car
so we will have
now we have
so from above equation
so from above equation work done by external force is given as
Answer:
0
Explanation:
The object would be neutral. There are equal numbers of protons and electrons, so the positive and negative charges cancel one another.
