Question

if the earth shrinks 50% of its real radius its mass remaining the same the weight of a body on the earth will in terms of % increase or decrease by?
​

Answer 1

Answer:

Explanation:

If earth really shrinks 50 % of its real radius and if mass is same then anyone's body weight on earth would increase about 30% due to the increased gravitation of earth.As because gravitation of any planet depends on its mass concentration.and as there earth's mass would be same but it's radius would shrink then there would be the more concentration of mass in less volume hence there would be increase in earth's gravity and anyone body's weight also..
