Question

An isosceles triangular plate of mass m and base l the angle of apex is 90degree and the apex lies at origin

Answer 1

Thank you for asking this question. The options for this question are missing:

1) ml^2/24

2)ml^2/12

3)ml^2/8

4)ml^2/6

Answer:

Let axis of rotation pass through hypotenuse.

Considering rotation about hypotenuse

We know square which passes through the diagonal will be

=  mi

= ml ^ 2/6

If mass of sq is m now triangle's mass will be the half of the hypotenuse

= ml ^ 2/12

Now we will apply perpendicular axis to the base as well as to the perpendicular the final answer would be:

ml^2/24

If there is any confusion please leave a comment below.
