Hello everyone we are going to understand this question here give it in the question there is two wheel mass of each wheel is one kg mass of first wheel that is represented by m1 which is 1 kilogram mass of second wheel mass of second wheel that is represented by m2 which is also 1 kilogram radius of 1st wheel, radius of 1st wheel that is represented by r1, which is 0 .5 meter.
01:01
And radius of 2nd wheel, radius of 2nd wheel that is represented by r2, which is 1 meter.
01:19
Applied force, f1, that is given 1 newton.
01:31
And value of f2 that we have to find and condition is angular acceleration is same for both wheel.
01:42
Angular acceleration of first wheel is equal to angular acceleration of first wheel equal to angular acceleration of second wheel.
02:06
Angular acceleration of second wheel of second wheel so we know that torque tau is equal to i into alpha that is f1 r1 and tau 2 that is this is i 1 and this is i 2 moment of nursery of first wheel is i 1 and moment of of second wheel that is i2 i2 into alpha is equal to f2 into r2 here it is given that alpha is same so from this we can write this is equation 1 and this is equation 2 from equation 1 and 2 we can write that alpha 1 is equal to alpha 2 so we can write f1 r1 upon i 1 is equal to f2 r2 upon i 1 is now, substituting the value in this, so here we can write, value of f1 is given 1 newton, value of r1 is given 0 .5, value of i1, that is m into m1 into r1 square upon 2.

Moment of inertia of veil about the circle, that is m1r1 square upon 2...
