when a spring is divided into two parts in the ratio 1:2 does it mean if we take one to be spring constant to be k1 the other becomes 2k1?
no spring constant depends on nature of materials
k(spring constant) inversly proportional to l(length) ...
k1/k = L/L1
length of two parts are L/3 , 2L/3
comparing spring constant of each part with original we get
k1 = 3k (spring constant of smaller part)
k2 = 3k/2 (spring constant of larger part)
Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
