A small block of wood of relative density 0.5 is submerged in water at a depth of 5 m When the block is released it starts moving upwards, the acceleration of the block is `(g=10ms^(-2)`)

Options

A. `5ms^(-2)`
B. `10ms^(-2)`
C. `7.5ms^(-2)`
D. `15ms^(-2)`

Explanation

To solve the problem of the small block of wood submerged in water, we can follow these steps:

### Step 1: Understand the Given Information
- Relative density of wood (ρ_wood/ρ_water) = 0.5
- Depth of submersion = 5 m
- Acceleration due to gravity (g) = 10 m/s²

### Step 2: Calculate the Density of Wood and Water
