My answer was 1470 Newtons, but I want to see if that is correct.

thanks in advance.

I found a 3" long, dark brown, VERY thin worm crawling on my ceiling, with tiny hairs all over it, and 2 antennae on its head. It is much much thinner than an earthworm, more like the diameter of a thin string. Any ideas what it is? Should i be cringing with fear? Thanks.
