The mass of a load is doubled while the force acting on it is halved. The resulting acceleration of the load is
A
quadrupled
B
quartered
C
halved
D
doubled
Verified Correct Answer: B.
Physical Principles & Numerical Solution
Force = mass x acceleration
but force was halved = 1/2 and mass doubled = 2 ( assuming that force and mass are 1N and 1kg respectively)
f = ma = \(\frac{1}{2}\) = 2 x a
dividing both sides by 2
a = \(\frac{1}{2} \times\frac{1}{2} = \frac{1}{4}\)
