41.
If α is the angle between the polar ray and the tangent at the point of commencement of a lemniscate curve, the equation of the curve, is
l = ksin α
l = ksin 2α
l = ksin 3α
l = ktan 2α
l = kcos 2α

The shortest distance between the point of commencement and point of a tangent I'm circular curve is?

Ashish Aryal said:   6 years ago
Option B is the correct answer.

Shahid said:   6 years ago
At the point of commencement. The curve takes only &alpha angle. not 2* α. So, option A is the right one.

HGH said:   6 years ago
Yes, B is the right.

Rajashri said:   7 years ago
The correct answer is B.

Kuldip said:   7 years ago
B is the right answer. I too agree.

Vishal said:   7 years ago
I think the correct Answer is B.

Tanu said:   8 years ago
Option (b) will be correct, as the length of lemniscate curve is:
L=3.934r√(sin2a).

Garry said:   8 years ago
The Correct answer is E.
