Answer:
Explanation:
It is said to be in equilibrium about the fulcrum . It is the principle of moments.
Answer:
m₁ (R +ℓ/2) / /( m₁ + m₂ )
Explanation:
We shall consider centre of the club's head as origin .
The centre of mass of the rod attached with sphere will be away from the centre of sphere by a distance
= R + ℓ /2 and its mass is m₁
mass of sphere is m₂ and distance of its centre of mass from origin is zero
So required CM = m₁ x₁ + m₂ x₂ / ( m₁ + m₂ )
= m₁ (R + ℓ /2) + m₂ x 0 /( m₁ + m₂ )
= m₁ (R +ℓ/2) / /( m₁ + m₂ )
