Question

pls solve fast. correct opt only. pls dont give wrong ans :(

Answer 1

Answer:

Value of x for angular acceleration equation will be root 2

$x = \sqrt{2}$

Answer 2

Answer:

√2

Explanation

here,

angular velocity 'ω' depends on rotated angle θ as,

ω=sinθ

differenciating on both sides with respect to time

d(ω)/dt=cosθ

or,α=cosθ  {d(ω)/dt=α(angular acceleration)}

now at θ=π/4

α=cos(π/4)

=1/√2

now

1/x=1/√2

x=√2
