Answer:
the intensity will be 4 times that of the earth.
Explanation:
let us assume the following:
intensity of light on earth =J
distance of earth from sun = d
intensity of light on other planet = K
distance of other planet from sun =
(from the question, the planet is half as far from the sun as earth)
from the question the intensity is inversely proportional to the square of the distance, hence
- intensity on earth : J =

J
= 1 ... equation 1
- intensity on other planet : K =
(the planet is half as far from the sun as earth)
K
= 1 ....equation 2
- equating both equation 1 and 2 we have
J
= K
J
= K
J = 
K = 4J
intensity of light on other planet (K) = 4 times intensity of light on earth (J)
