Question

Find the power in lifting a body of mass 10kg to height of 10m in 10sec.​

Answer 1

Explanation,

Given,

• Mass (m) of a body is 10 kg.
• Height (h) = 10 m
• Time taken (t) = 10 sec
• Acceleration due to gravity (g) = 10 m/s²

To Find,

• The power in lifting a body.

Solution,

Applying power formula,

P = W/t

⟹ P = mgh / t

[ Put the values ]

⟹ P = 10 × 10 × 10 / 10

⟹ P = 1000/10

⟹ P = 100 watt

Therefore,

The power in lifting a body is 100 watt.

$\huge\color{orange}{\textbf{\textsf{SOLUTION :-}}}$

Applying power formula,

P = W/t

=> P = mgh/t

=> P = 10 × 10 × 10/10

=> P = 1000/10

=> P = 100 W

Hence, the power in lifting a body is 100 W.
