(a) more angular acceleration will be produced (b) more angular acceleration will be produced
in(a)
in(b)
(c) same angular acceleration will be produced in both conditions
(d) information is incomplete​

Answer 1

Answer:

b

Explanation:

torque = Inertia × alpha

alpha = torque / Inertia

alpha is inversely proportional to inertia

in fig (b) moment of inertia is smaller

therefore acceleration (alpha) is greater

b) more angular acceleration will be produced in (b)
