With a diameter that's 11 times larger than Earth's, Jupiter is the largest planet.
Jupiter is the biggest planet in the solar system. No wonder ancient astronomers named it after Jupiter, King of the Roman gods. More than 1,000 planets the size of Earth could fit inside Jupiter. A tunnel through Jupiter would be 11 times longer than a tunnel through Earth. A trip around Jupiter equator would take 6 times longer than a trip around the Earth's equator. 
        
                    
             
        
        
        
let the distance of pillar is "r" from one end of the slab
So here net torque must be balance with respect to pillar to be in balanced state
So here we will have

here we know that
mg = 19600 N
Mg = 400,000 N
L = 20 m
from above equation we have



so pillar is at distance 10.098 m from one end of the slab
 
        
             
        
        
        
Answer:
The value is  
 
Explanation:
From the question we are told that 
 The wavelength is 
 The velocity is 
 The mass of electron is 
Generally the energy of the incident light is mathematically represented as 
 
Here c is the speed of light with value  
 
 h is the Planck constant with value 
 So 
 
=> 
Generally the kinetic energy is mathematically represented as 
 
=> 
=> 
Generally the ionization energy is mathematically represented as 
 
=>
