Forces on Europa's surface

Hi, I'm trying to understand how the gravitational force from Jupiter would affect the force an object would experience on the surface of Europa and have not been able to find the answers to these questions online.

What is the range of force on Europa's surface from the gravitational pull from Jupiter (at Europa's periapsis and apoapsis)? Is it ever stronger than Europa's own gravity (1.314 m/s2)?
If an object on Europa's surface is on the exact opposite side of Jupiter, does it experience a greater downward force? (e.g. net force Europa gravity + gravitational pull from Jupiter)?

Thanks!

Radiotrophic organisms under the ice in Europa

Hello, I recently stumbled upon this article about Chernobyl, it was about this fungus that can perform a process known as radiosynthesis, which is analog to chemosynthesis or photosynthesis, but instead uses radiation to generate nutrients.

So I wonder if some of this could have evolved in Europa, given all the radiation available, Is there enough radiation under the ice? if so could this give Europa the capability of supporting a larger ecosystem, the radiotrophic organisms would be the primary organisms and they would be not just around the hydrothermal vents, but everywhere if enough radiation reaches the water.

What do you think? is this a possibility? Or am I just reading too much stuff that I don't understand?
