Question

A plastic sphere of radius 0.04 m & mass 0.01 kg is immersed in a container of water. It is attached to a string that is attached to the bottom of container. Find tension in the string.

Answer 1

Explanation:

To calculate displacement, simply draw a vector from your starting point to your final position and solve for the length of this line. If your starting and ending position are the same, like your circular 5K route, then your displacement is 0. In physics, displacement is represented by Δs.

Answer 2

Answer:

Explanation:F(b) = T + mg

=> T = F(b) - mg. (1)

F(b) = P(w) V g = 1000 × 4÷3 × π × ((0.04)^3) × g = 2.6 N

From (1) and (2),

T = F(b) - mg

=> 2.6 - 1 = 1.6 N ( Ans. )

Here 'P' refers to density & F(b) refers to buoyant force .....
