Question

the force constant of a spherical is 10 Newton per metre calculate the amount of the work done 10cm to 0.5cm​

Answer 1

Answer:

Question 1.1:

What is the force between two small charged spheres having charges of 2 × 10−7 C and 3 × 10−7 C placed 30 cm apart in air?

ANSWER:

Repulsive force of magnitude 6 × 10−3 N

Charge on the first sphere, q1 = 2 × 10−7 C

Charge on the second sphere, q2 = 3 × 10−7 C

Distance between the spheres, r = 30 cm = 0.3 m

Electrostatic force between the spheres is given by the relation,

Where, ∈0 = Permittivity of free space

Answer 2

Explanation:

F=kvrη.
