Define force constant of a spring & write its dimension.

What is force constant of a spring?

What will be the change in the force constant of a spring if its length is doubled?

The force constant of a spring is K. The spring is divided into three equal part. What will be the value of force constant of each part?

K is a force constant of a spring. The work done in increasing its extension from l_1 to l_2 will be

Force constants of two springs are k_1 and k_2 . What will be the equivalent force constant of the spring system when the springs are joined in a parallel combination?

The force constant of a spring is k. The spring is cut into three equals parts. Find the force constant of each part.

The force constant of a spring of length l is k. the spring is cut into two parts of lenghts l_1 and l_2 . IF l_1=nl_2 , then find the spring constants k_1 and k_2 of the two parts.n is an integer.

Length and force constant of a spring are L and K respectively. When a force T is applied on it an elongation x is produced. Now the spring is cut into two equal parts and they are connected parallel with each other and the same force T is applied on it. What will be the elongation now?

Define electric potential and write down its dimensional formula.
