Question

A bag of wheat 200 kg. To what height should it be raised so that the potential energy may be 9800 joules???​

Answer 1

$\huge\fbox{\dag Answer \dag}$

m = 200 kg

g = 9.8 ms-2

PE = 9800 J

PE = m × g × h

9800 J = 200 kg x 9.8 ms-2 x h

h = 9800

J = 200 kg x 9.8 ms-2

h = 5 m

Thus, the bag of wheat should be raised to a height of 5 m.

Answer 2

➽ Question :-

A bag of wheat 200 kg. To what height should it be raised so that the potential energy may be 9800 joules???

➽ Answer:

• the bag of wheat should be raised to a height of 5 metres .

➽ Given :-

• Mass of the bag = 200 kg  
• Potential energy = 9800 J  
• Gravity = 9.8 m/s²

➽ To Find :-

• Height = ?

➽ Solution :-

As we know that

• P.E = mgh

where,

• P = Potential energy
• m = Mass
• g = gravity
• h = Height

Now, putting the values in the above formula we get,

➞ 9800 = 200 x 9.8 x h

➞ h = 9800 / 200 x 9.8

➞ h = 5 m

Hence, the bag of wheat should be raised to a height of 5 metres .
