HEAD-ON COLLISION:
"If the centers of the colliding bodies stay moving along the similar straight line, the collision is said to be head-on collision".
What is the work done to take a particle of mass m from surface of the earth to a height equal to 2R (R=radius of earth )? Ans) Initial PE= - GMm/R Final PE = - GMm/3R
The minimum real charge on any particle which can exist is: (1)1.6x 10 -19 coulomb (2) 1.6x 10 -10 coulomb (3)4.8 x 10 -10 coulomb (4)Zero Ans: (1)1.6x 10 -19 c
