Question

A mass of 5 kg is placed an a hight of 30 meter from the ground.potential energy of the body in joules is?

Answer 1

Answer:

Step-by-step explanation:

P.E=mgh

mass= 5kg

height =30 m

g=9.8

P.E=5 x 30 x 9.8 =1470 joules

if u take g as 10

P.E=1500 joules

Answer 2

$\color{darkblue}\underline{\underline{\sf Given-}}$

• Mass (m) = 5kg
• Height (h) = 30m

$\color{darkblue}\underline{\underline{\sf To \: Find-}}$

• Potential Energy (U)

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

❏ Potential Energy (U)

$\color{violet}\bullet\underline{\boxed{\sf Potential\: Energy=mgh}}$

$\implies{\sf U = 5×10×30}$

$\color{red}\implies{\sf U = 1500J}$

$\color{darkblue}\underline{\underline{\sf Answer-}}$

Potential Energy of body is $\color{red}{\sf 1500J}$
