as we know tha momentum is product of mass and velocityi.e p=mv but here in this question velocity changes from 5m/s to 20 m/s so here formula becomes
p=(final velocity -initial velocity )mass
so (20-5)6=90kgm/s ANS
Answer:
Explanation:
According to Coulomb's law, the magnitude of the force (F) between two objects with the same charge(+Q), separated a distance (d) apart, is defined as:
Here k is the Coulomb constant. The charge on each object is doubled, that is :
