Hello students, we are given with unit of force is equal to 10 newton and energy is equal to 100 joule and velocity is equal to meter per second and we have to find the unit for length mass.
00:35
So, first let us check energy.
00:37
Energy is equal to force into distance.
00:42
So, energy is 100 joule is equal to what is force 10 newton into distance.
00:50
Therefore, d is equal to 100 kilogram joule is otherwise written as kilogram meter square second per second square divided by 10 newton is 10 into kilogram meter per second square.
01:10
Therefore, when this cancels 10 will come kilogram kilogram cancels meter 1 meter cancels second square second square cancels therefore distance is equal to 10 meter 1 meter is remaining here therefore 10 meter that is this is the unit of length.
01:33
Next we know that velocity is equal to distance traveled by time taken.
01:40
So, velocity is given as 5 meter per second is equal to 10 meter per divided by t.
01:49
Therefore, t is equal to 10 meter divided by 5 meter per second.
01:56
So, when it cancels 2 meter meter cancels and second comes to numerator this is 2 seconds...
